AIM Photonics has had an active multi-project wafer (MPW) program since 2015 and in our latest work we will present our new integration aimed at the reduction of waveguide propagation losses. Often low losses are prioritized for passive MPWs runs but

Conventional electronically-steerable phased-array antenna systems suffer from increasingly complicated control schemes to allow for narrowband RF steering. A phased array antenna architecture was previously presented which provides for wideband stee

An RF-Photonic phased array antenna beamformer was previously demonstrated using cascaded fiber Bragg gratings with 1 x 2 couplers for true-time-delay beamforming. This work's focus is to design, build, and test an integrated Si-photonic beamforming

A sub-wavelength grating (SWG) coupler is designed for coupling from a lensed fiber to an on-chip SiN waveguide. The designed SWG is compared with an inverse taper and analyzed for fabrication inaccuracies and misalignment conditions.

An integrated RF-photonic link that consists of a slow-light enhanced silicon (Si) electro-optic modulator, a single mode Si optical waveguide and a silicon-germanium (SiGe) photodetector was fabricated using a Si photonic standard foundry service. T

Interleaved doped Mach-Zehnder Modulators (MZMs) are one solution to attaining higher modulation efficiencies compared with lateral junction structures, due to greater modal overlap with the depletion regions of the PN junctions. In this work, we pre
