The method includes securing at least portions of a perimeter of the optical film in a first plane so that the secured portions do not move relative to one another; and stretching the optical film by displacing a portion of the optical film along at least a first direction perpendicular to the first plane such that one of a radial and circumferential stretching of the optical film is substantially constant from a center to the perimeter of the optical film, and the other one of the radial and circumferential stretching of the optical film substantially changes from the center to the perimeter of the optical film. The optical film is a reflective polarizer including a plurality of alternating polymeric layers.

An optronic transceiver module is disclosed. The optronic transceiver module includes an m to n main optical coupler capable of splitting a downlink signal into n downlink optical signals of the same power to be transmitted in n optical fibres, a first uplink optical coupler capable of splitting an uplink signal into two optical signals split according to a predetermined reference power ratio and delivering a low-power signal and a high-power signal, a first power measurement photodiode delivering a power measurement associated with a first low-power signal, the main optical coupler being capable of aggregating the high-power optical signal and a second uplink optical signal representative of an optical signal received via a second optical fibre, into an aggregated uplink optical signal.

A slope gain equalizer that corrects a slope of a gain characteristic of an optical signal in a predetermined wavelength bandwidth. An interference filter, which allows insertion losses in a predetermined wavelength region to be inclined in opposite directions between a transmitting direction and a reflecting direction from a short wavelength side to a long wavelength side, is arranged between a dual-core fiber collimator and a single-core fiber collimator facing each other on an optical axis. An optical signal of a predetermined bandwidth inputted from a first or second optical fiber held by the dual-core fiber collimator is reflected by the interference filter and outputted from the second or the first optical fiber. An optical signal inputted from a third optical fiber held by the first optical fiber or the single-core fiber collimator is transmitted through the interference filter and outputted from the third or the first optical fiber.

Components and arrangements for managing wave division multiplexing (WDM) filters of fiber optic networks. A flexible a substrate is used to fix a fiber routing scheme that corresponds to a cascading arrangement of WDM filters. The WDM filters can be packaged as a standalone unit for easier handling and splicing of fiber pigtails to the pre-arranged fiber routing scheme.

An optical module as disclosed includes an aligning bridge, an optical de-multiplexer and a lens array. The aligning bridge has a first section and a second section opposite to the first section. The optical de-multiplexer is on the first section of the aligning bridge. The optical de-multiplexer comprises a plurality of filters configured to transmit a plurality of light beams of different wavelengths. The lens array is on the second section of the aligning bridge. The lens array comprises a plurality of input ports aligned with the filters and configured to receive the light beams from the filters.

A curved reflective has at least one location having a radius of curvature in a range from about 6 mm to about 1000 mm. Each location on the reflective polarizer has a maximum reflectance greater than about 70% for a block polarization state, a maximum transmittance greater than about 70% for an orthogonal pass polarization state, and a minimum transmittance for the block polarization state. For a continuous first portion of the reflective polarizer extending between different first and second edges of the reflective polarizer and defining disjoint second and third portions of the reflective polarizer, the minimum transmittance of the reflective polarizer for the block polarization state is higher at each location in at least 70% of the first portion than at each location in at least 70% of the second portion and at each location in at least 70% of the third portion.

An optical communication system that includes terminals that operate with different, widely separated wavelengths in which a terminal in the system may be configured to function in both a first operational mode and in a second operational mode. For example, a terminal according to the techniques of this disclosure may communicate with full duplex communication by transmitting a first optical wavelength and receiving a second optical wavelength while in the first operational mode. The same terminal may be reconfigured to transmit the second optical wavelength and receive the first optical wavelength while in the second operational mode. In some examples, the terminal may be located in a spacecraft, such as an orbiting satellite or other vehicle, and may communicate with other terminals such as airborne terminals, terminals located at ground station on the Earth's surface, or with terminals located in other spacecraft.

An interference filter module comprises two optical fiber collimators arranged on an optical axis so as to be opposed to each other, interference filters, and a casing including a main body portion and filter holding portions to be mounted into the main body portion, which are configured to hold the interference filters. Two interference filters including a kth filter when counted from a front end and a k-th filter when counted from a rear end are determined as a k-th set. The two interference filters of the k-th set are accommodated in two filter holding portions, each of which is a k-th holding portion when counted from the front end and the rear end, respectively. The two filter holding portions have rotation axes in directions orthogonal to a fore-and-aft direction and are rotatably held by the casing. The rotation axes of the filter holding portions are orthogonal to each other.

A solar module assembly includes a frame having an upper portion encompassing an area and a mid portion disposed below the upper portion. A plurality of solar panels is arranged in a string, sandwiched between two transparent panes forming a single string panel. The solar panels occupy less than the area of the upper portion. Each of the plurality of solar panels has a pair of opposing edges. A reflector is mounted on the mid portion to reflect light selectively.
