Created using Optoscribe’s proprietary high-speed laser writing technique, OptoCplrLT™ is designed to overcome fiber-to-SiPh photonic integrated circuit (PIC) coupling challenges to enable high volume automated assembly and help drive down costs.
Optoscribe’s OptoCplrLT™ uses low loss light turning curved mirrors, which are formed in the glass, to direct the light to or from the SiPh grating couplers. This prevents the need for bend-tolerant fiber solutions, which are often expensive, challenging to manufacture and have some significant limitations in size and profile.
OptoCplrLT™ has a low-profile interface, ~1mm device height and ~1.5mm with cap, which allows compact interface layouts that alleviate packaging constraints and helps address footprint challenges. Optoscribe’s solution is also compatible with industry-standard materials and processes; for example, the glass chip has a coefficient of thermal expansion matched to the silicon chip, helping to maximize performance.
