Abstract
Described herein are systems and techniques for providing photonic devices having glass substrates for use in an optical interconnect system. The photonic devices comprise a glass substrate and one or more optoelectronic assemblies coupled through openings of the glass substrate. Waveguides of the optoelectronic assemblies may be optically coupled with waveguides of the glass substrate forming an optical network through the glass substrate. The assembly waveguides may be optically coupled to the glass waveguides through pluggable optical couplers, evanescent coupling, and/or edge coupling.
Claims20
A photonic device, comprising:
- a glass substrate, having a first surface and a second surface opposite the first surface, comprising:
- an optical network having one or more glass waveguides;
- and
- a plurality of openings extending through the glass substrate from the first surface to the second surface;
- and
- a plurality of assemblies secured within respective ones of the plurality of openings, each assembly comprising:
- a photonic integrated circuit (PIC) having a waveguide optically coupled to at least one glass waveguide of the one or more glass waveguides;
- and
- an application-specific integrated circuit (ASIC) attached to the PIC.
A method of assembling a photonic device, the method comprising:
- obtaining a plurality of photonic integrated circuits (PICs), each PIC having a waveguide patterned thereon;
- attaching a plurality of application-specific integrated circuit (ASICs) to respective PICs of the plurality of PICs to form a plurality of assemblies;
- and
- inserting the plurality of assemblies into respective openings of a glass substrate, wherein the openings extend from a first surface of the glass substrate to a second surface of the glass substrate opposite the first surface, wherein inserting the plurality of assemblies into the respective openings comprises optically coupling glass waveguides of the glass substrate to respective waveguides of the PIC.
