Abstract
Roughly described, an integrated optical device includes both a PLC chip and an attached SiPh chip. The PLC chip has a PLC waveguide which terminates at an end facet. The SiPh chip has a SiPh waveguide which includes a Bragg grating which diffracts light from the SiPh waveguide toward the PLC chip. The PLC chip also has a turning mirror to reflect light emitted from the Bragg grating onto the end facet of the PLC waveguide. The Bragg grating is designed to direct light emitted from the Bragg grating into the end facet of the PLC waveguide so that after reflecting off the turning mirror the light focuses within one Rayleigh distance of the end facet of the PLC chip.
