Cryogenic Optical Packaging Using Photonic Wire Bonds

In this paper, our partner at UBC, Professor Lukas Chrostowski and team use photonic wire bonding (PWB) to make reliable and efficient optical connections between single mode fiber (SMF) and silicon photonic circuits down to 970 mK. The results presented show that...

Photonic Wirebonds (PWB) and 3D-printed freeform-lenses allow to fabricate widely-tunable, record-low “Sub-kHz-linewidth external-cavity laser (ECL) with Si3N4 resonator used as a tunable pump for a Kerr frequency comb

Combining optical gain in direct-bandgap III-V materials with tunable optical feedback offered by advanced photonic integrated circuits is key to chip-scale external-cavity lasers (ECL), offering wideband tunability along with low optical linewidths. External feedback...
