Planar lightwave circuits with a polymer coupling waveguide optically coupling a planar waveguide over a first region of a substrate to an optical component, such as a laser, affixed to a second region of the substrate. The coupling waveguide may be formed from a polymer layer applied over the planar waveguide and optical component such that any misalignment between the two may be accommodated by patterning the polymer into a waveguide having a first end aligned to an end of the planar waveguide and a second end aligned to an edge of the optical component. In embodiments, the polymer is photo-definable, such as a negative resist, and may be patterned through direct laser writing. In embodiments, the optical component is a thin film affixed to the substrate through micro-transfer printing. In other embodiments, the optical component is a semiconductor chip affixed to the substrate by flip-chip bonding.

The present invention provides a direct laser writing fabrication method and system for devices having periodic refractive index modulation structures, for example, Bragg gratings. By focusing a modulated pulsed laser beam into a transparent material substrate, a path of laser modified volumes can be formed with modified refractive index compared with the unprocessed material. Modulation of exposure conditions provides periodic or modified periodic waveguide structures such that the waveguide structures exhibit grating responses and can be used for a variety of optical applications, for example, as spectral filters, Bragg reflectors, grating couplers, grating sensors, or other devices. The method enables direct one-step fabrication and integration of periodic or modified periodic refractive-index modulation devices together with other optical waveguiding devices to enable low-cost, multifunctional one-dimensional, two-dimensional or three-dimensional optical circuit fabrication of simple and complex optical systems.

Apparatuses having a plurality of optical duplex and parallel connector adapters, such as MPO connectors and LC adapters, where some adapters connect to network equipment in a network and others to servers or processing units such as GPUs, incorporate internal photonic circuit with a mesh. The light path of each transmitter and receivers is matched in order to provide proper optical connections from transmitting to receiving fibers, wherein complex arbitrary network topologies can be implemented.

Embodiments described herein may be related to apparatuses, processes, and techniques directed to dense integration of PICs in a substrate using an optical fanout structure that includes waveguides formed within a substrate to optically couple with the PICs at an edge of the substrate. One or more PICs may then be electrically with dies such as processor dies or memory dies. The one or more PICs may be located within a cavity in the substrate. The substrate may be made of glass or silicon. Other embodiments may be described and/or claimed.
