Abstract: A temperature-controlled photodetector sub-system is described. The temperature control element allows the operation of the photodetector at a desired temperature. The temperature control element can be a heater or a cooler. In some cases, the photodetector is a germanium photodetector. In some cases a temperature measuring device is provided. In some cases, a control circuit is used to control the temperature of the germanium photodetector within a temperature range, or at a temperature of interest. An advantage provided by the apparatus described is the operation of the photodetector so that the responsivity of the germanium detector can be held at essentially a constant value.

Abstract: An architecture for a fiber optic communication system that uses only two levels of switches, Tier 1 and Tier 3, is described. The architecture allows one to omit the conventional Top of Rack switch level and the conventional Tier 2 switch level while maintaining performance and throughput. The cost to construct and install the improved switch architecture is lower than the cost of the conventional architecture. There are also described a number of transceivers that are suitable for use in the architecture disclosed. The transceivers employ silicon PIC chips that include high contrast silicon waveguides ion the chip and that connect to various configurations of optical fibers. The transceivers provide enhanced switching capacity with fewer devices.

Abstract: A skew compensation apparatus and method. In an optical system that uses optical signals, skew may be generated as the optical signals are processed from an input optical signal to at least two electrical signals representative of the phase-differentiated optical signals. A compensation of the skew is provided by including an optical delay line in the path of the optical signal that does not suffer the skew (e.g., that serves as the time base for the skew measurement). The optical delay line introduces a delay Tskew equal to the delay suffered by the optical signal that is not taken as the time base. The two signals are thereby corrected for skew.

Abstract: A light shield may be formed in photonic integrated circuit between integrated optical devices of the photonic integrated circuit. The light shield may be built by using materials already present in the photonic integrated circuit, for example the light shield may include metal walls and doped semiconductor regions. Light-emitting or light-sensitive integrated optical devices or modules of a photonic integrated circuit may be constructed with light shields integrally built in.

Abstract: A qualification apparatus for a photonic chip on a wafer that leaves undisturbed an edge coupler that provides an operating port for the photonic devices or circuits on the chip during normal operation in order to not introduce extra loss in the optical path of the final circuit. The qualification apparatus provides an optical path that is angled with regard to the surface of the chip, for example by using a grating coupler. The qualification apparatus can be removed after the chip is qualified. Optionally, the qualification apparatus can be left in communication with the chip and optionally employed as an input port for the chip after the chip has been separated from other chips on a common substrate.

Abstract: A fiber alignment or “fiberposer” device enables the passive alignment of one or more optical fibers to a photonic integrated circuit (PIC) device using mating hard-stop features etched into the two devices. Accordingly, fiber grooves can be provide separate from the electrical and optical elements, and attached to the PIC with sub-micron accuracy. Fiberposers may also include a hermetic seal for a laser or other device on the PIC. All of these features significantly reduce the typical cost of an actively aligned optical device sealed in an hermetic package.

Abstract: A composite optical waveguide is constructed using an array of waveguide cores, in which one core is tapered to a larger dimension, so that all the cores are used as a composite input port, and the one larger core is used as an output port. In addition, transverse couplers can be fabricated in a similar fashion. The waveguide cores are preferably made of SiN. In some cases, a layer of SiN which is provided as an etch stop is used as at least one of the waveguide cores. The waveguide cores can be spaced away from a semiconductor layer so as to minimize loses.
