FIBER MICROPOSITIONER
A micropositioner is provided. The micropositioner can include a suspension system with a support element that is connected to a base by first and second sets of flexures. The first and second sets of flexures permit movement of the support element within first and second dimensions respectively, while preventing movement of the support element in a third dimension that is orthogonal to the first and second dimensions. More particularly, the first set of flexures can include first and second flexures that are opposite one another and configured such that movement of the support element in the first dimension is allowed, but movement of the support element in the second and third dimensions is prevented. The second set of flexures can include third and fourth flexures that are opposite to one another and configured such that movement of the support element in the second dimension is allowed, but movement in the first and third dimensions is prevented. The micropositioner may be included in a system for pointing a laser beam.
LENS-LESS LASER MICRO-PACKAGE ASSEMBLY
An optoelectronic assembly may include a photonic integrated circuit (PIC) with a top surface and a laser with a top surface and a bottom surface. The optoelectronic assembly may also include a housing configured to cooperate with the PIC to one or both of house and support one or more components. The housing may include a PIC mount including a first surface to interface with the top surface of the PIC, and a laser mount including a second surface to interface with the top or bottom surface of the laser. The first surface and the second surface may be parallel to each other.
OPTICAL HEAD AND MEASURING APPARATUS
An optical head includes a first module that concentrates pump light and Stokes light on a first point; a second module that collects CARS light from the first point; and a third module that supports the first module and the second module. The first module includes: a high rigidity first frame; and a first optical system including a plurality of optical elements fixed to the first frame. The second module includes: a high rigidity second frame; and a second optical system including a plurality of optical elements fixed to the second frame. The third module includes a high rigidity third frame that fixes the first frame and the second frame.
MICROMECHANICALLY ALIGNED OPTICAL ASSEMBLY
An optical assembly includes a combination of laser sources emitting radiation, focused by a combination of lenses into optical waveguides. The optical waveguide and the laser source are permanently attached to a common carrier, while at least one of the lenses is attached to a holder that is an integral part of the carrier, but is free to move initially. Micromechanical techniques are used to adjust the position of the lens and holder, and then fix the holder it into place permanently using integrated heaters with solder.
Methods for optical system manufacturing
Systems and methods described herein relate to the manufacture of optical elements and optical systems. An example method includes providing a first substrate that has a plurality of light-emitter devices disposed on a first surface. The method includes providing a second substrate that has a mounting surface defining a reference plane. The method includes forming a structure and an optical spacer on the mounting surface of the second substrate. The method additionally includes coupling the first and second substrates together such that the first surface of the first substrate faces the mounting surface of the second substrate at an angle with respect to the reference plane.
CORE ADJUSTMENT METHOD
A condenser lens for collecting a laser beam (300) is disposed between the laser oscillator and the incident end surface of the optical fiber. The laser beam (300) is divided into a plurality of beams (303, 304). The power of the laser beam (304) is measured and maximized by adjusting the position of the condenser lens. The FFP of the laser beam (303) is measured and minimized by adjusting the position of the condenser lens. These adjusted positions are stored as the first and second lens positions. The FFP of the laser beam (303) is measured while the condenser lens is being moved between these positions so as to make the BPP not more than a predetermined value.
OPTICAL MODULE
An optical module includes a casing, a substrate fixed to a first surface of the casing, the first surface is included in an inside of the casing, an optical element disposed on the substrate and includes at least one of a light receiving element and a light emitting element, a lens block disposed on the inside of the casing, and optically couples an optical connector coupled to an optical transmission line and the optical element to each other, and a male screw disposed so as to pass through a hole disposed in a second surface of the casing, the second surface being opposite from the first surface, and a hole disposed in the lens block, and changes a distance between the second surface and the lens block when the male screw is rotated.
Fiber optic cable to emitter/detector alignment apparatus and method
An apparatus for aligning a fiber optic connector with a detector or an emitter in a housing includes a stationary base mountable on the housing, a mobile stage movable relative to the stationary base, and spring-loaded adjustment screws on the stationary base oriented orthogonally relative to one another to adjust a position of the mobile stage in x and y directions. The stationary base and mobile stage include central openings that allow the adjustment mechanism to be positioned around the fiber optic connector. The stationary base and mobile stage also include lateral slots extending inwardly from their respective peripheral edges to their respective central openings to allow passage of a fiber optic cable when positioning or removing the apparatus.
LASER MODULE
A laser module has a base portion having a metal holding portion; a laser light source fixed to the base portion; an optical outputting portion deriving the laser light from a collimating optical system out of the base portion. The collimating optical system includes an input lens receiving the laser light from the laser light source; and an output lens receiving the laser light from the input lens and outputting the laser light to the optical outputting portion, each located in order from the laser light source. The input lens is a convex lens fixed in a first cylinder body made of metal and welded to the holding portion. The output lens is a convex lens having a focal point length longer than that of the input lens and held by the holding member glued to the base portion.
Assembly and method for aligning a light beam
An assembly and method for aligning a light beam that is exiting from a light source/guide are provided. The assembly includes an outer housing and an inner housing which is at least partially arranged inside the outer housing and is adjustably mounted to the outer housing. The inner housing accommodates and fixes the light source/guide such that the optical axis of the light beam is fixed relative to the longitudinal direction of the inner housing and such that different inclinations are adjustable between the longitudinal direction of the inner housing and the longitudinal direction of the outer housing in order to align the optical axis of the light beam relative to the longitudinal direction of the outer housing.
