Ipzz-040 99%

The mode‑locked lasers of IPZZ‑040 generate high‑repetition‑rate pulse trains suitable for frequency‑comb based ranging. Integrating a micro‑lens array on top of the waveguide mesh transforms the chip into a solid‑state lidar engine capable of > 200 kHz frame rates with < 1 cm resolution, opening pathways to automotive and drone applications.

A dedicated micro‑laser epitaxy step deposits InAs/InP quantum‑dot stacks directly on the silicon waveguide cores, forming monolithically integrated gain media. The lasers are subsequently processed with selective area growth to define ridge cavities and distributed Bragg reflectors (DBRs). The lasers are subsequently processed with selective area
