    Abstract: Embodiments described herein relate to techniques and configurations associated with a photonic apparatus (e.g., PIC) having a photodiode and a bypass capacitor disposed in a channel. In one instance, the apparatus includes a substrate in which at least first and second channels are formed. The first channel includes a first photodiode and a first capacitor coupled to the first photodiode, and the second channel includes a second photodiode and a second capacitor coupled with the second photodiode. The first and second capacitors are provided to assist with biasing the first and second photodiodes respectively and to isolate a signal output by the first and second photodiodes from interference provided by the power supply associated with the apparatus. Additional embodiments can be described and claimed.

    Abstract: Optical receiver packages and device assemblies that include photodetector (PD) chips having focus lenses monolithically integrated on PD die backsides are disclosed. An example receiver package includes a support structure, a PD die, and an optical input device. The PD die includes a PD, integrated proximate to a first face of the PD die, and further includes a lens, integrated on, or proximate to, an opposite second face. The first face of the PD die faces the support structure, while the second face (“backside”) faces the optical input device. The optical receiver architectures described herein may provide an improvement for the optical alignment tolerance issues, especially for high-speed operation in which the active aperture of the PD may have to be very small. Furthermore, architectures described herein advantageously enable integrating a focus lens in a PD die that may be coupled to the support structure in a flip-chip arrangement.

    Abstract: A single hybrid electrical/optical connector simultaneously forms both electrical and optical input/output connections by a single step engagement between elements on a connector and corresponding elements of the opposite gender on a mating connector. The connector can be surface-mounted on a circuit board, and a mating connector can be vertically pluggable onto the connector. The optical elements on the connector and/or the mating connector can be detachable, which can simplify assembly of a system that includes the circuit board. The hybrid electrical/optical connector has applications for optical transceivers. The hybrid electrical/optical connector includes a housing that extends laterally along a housing plane. The housing includes electrical and optical sockets thereon. In some examples, the electrical sockets and the optical sockets are laterally arranged on opposite sides of a division plane perpendicular to the housing plane.

    Abstract: A vertical total internal reflection (TIR) mirror and fabrication thereof is made by creating a re-entrant profile using crystallographic silicon etching. Starting with an SOI wafer, a deep silicon etch is used to expose the buried oxide layer, which is then wet-etched (in HF), opening the bottom surface of the Si device layer. This bottom silicon surface is then exposed so that in a crystallographic etch, the resulting shape is a re-entrant trapezoid with facets These facets can be used in conjunction with planar silicon waveguides to reflect the light upwards based on the TIR principle. Alternately, light can be coupled into the silicon waveguides from above the wafer for such purposes as wafer level testing.

    Abstract: Techniques for photonic demultiplexers are disclosed. In the illustrative embodiment, an output of an unbalanced interferometer formed from waveguides is positioned to the input of a slab grating, with several output waveguides collecting light in different wavelength ranges to create different channels for the demultiplexer system. In some embodiments, one or more auxiliary structures may be positioned near the input of the grating to change the structure of the spatial modes being provided as an input to the grating in order to alter the spectra of the output channels.
