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 for key application spaces such as Telecommunications and Quantum Technology, it is imperative to incorporate both low-loss waveguides and active devices on a single die. Within this work we have demonstrated a loss of 1.0 dB/cm in Si strip waveguides and 0.48 dB/cm in SiN waveguides, a reduction of 0.4-3.5 dB/cm and 1-1.5 dB/cm, respectively, when compared to other MPW foundries.
We present a novel, highly non-degenerate, heralded visible-telecom photon-pair source using an integrated system of nonlinear waveguides and photonic circuits. Thermo-optic modulation of the telecom single-photon-state is demonstrated for deployable quantum communication/networking systems.
We present foundry-fabricated thermo-optic phase shifters using visible wavelength silicon nitride (SiN) waveguides. A 500µm long phase shifter demonstrated a π phase shift at a Pπ≈120m W.
In this paper, we present CMOS-foundry-fabricated silicon nitride photonic structures at barium emission wavelengths - 493nm and 650nm. High mode-confinement, low propagation losses, and inverse-designed 3dB splitters are demonstrated.
