Abstract:
A photonic integrated circuit may be coupled to an optical fiber and packaged. The optical fiber may be supported by a fiber holder during a solder reflow process performed to mount the packaged photonic integrated circuit to a circuit board or other substrate. The optical fiber may be decoupled from the fiber holder, and the fiber holder removed, after completion of the solder reflow process.
Abstract:
A photonic interface for an electronic circuit is disclosed. The photonic interface includes a photonic integrated circuit having a modulator and a photodetector, and an optical fiber or fibers for optical communication with another optical circuit. A modulator driver chip may be mounted directly on the photonic integrated circuit. The optical fibers may be placed in v-grooves of a fiber support, which may include at least one lithographically defined alignment feature for optical alignment to the silicon photonic circuit.

Abstract:
An optical apparatus comprises an optical device (910) fabricated on a substrate (1902), an external-transfer optical waveguide (1930) fabricated on the substrate (1902) and/or on the optical device, and a transmission optical waveguide (1920). The optical device and/or the external-transfer waveguide are adapted for and positioned for transfer of optical power therebetween (end-transfer or transverse-transfer). The external-transfer waveguide and/or the transmission waveguide are adapted for transverse-transfer of optical power therebetween (mode-interference-coupled or adiabatic). The transmission waveguide is initially provided as a component mechanically separate from the substrate, device, and external-transfer waveguide. Assembly of the transmission waveguide with the substrate, device, and/or external-transfer waveguide results in relative positioning of the external-transfer waveguide and the transmission waveguide for enabling transverse-transfer of optical power therebetween. Optical power transfer between the device and the transmission waveguide through the external-transfer waveguide is thereby enabled. The transmission waveguide may preferably comprise a planar waveguide on a waveguide substrate.
Abstract:
An integrated circuit/optoelectronic packaging system (100) which comprises OE and IC components packaged to provide electrical input/output, thermal management, an optical window, and precise passive or mechanical alignment to external optical receivers or transmitters. A transparent insulating substrate having electrical circuitry in a thin silicon layer formed on its top side is positioned between the optical fiber and the optoelectronic device such that an optical path is described between the optoelectronic device and the optical fiber core through the transparent insulating substrate. Arrays of fibers may be coupled to arrays of optoelectronic devices through a single transparent substrate. The optoelectronic devices are mounted on the transparent insulating substrate in a precise positional relationship to guide holes in the substrate. The optical fibers are fixed in an optical fiber connector and are held in a precise positional relationship to guide holes in the connector. Alignment is accomplished with complementary guide pins that pass through guide holes in the fiber optic connector and in the transparent substrate. The method is used for packaging optoelectronic devices (e.g.,VCSELs, photodetectors) electrically connected to integrated circuitry into a small scale package which is compatible with high volume automated assembly, handling, burn-in and testing. Automated testing includes electrical performance, optoelectronic performance an optical coupling between small scale package and optical fibers or waveguides.
