Abstract
A photonic integrated circuit for coupling a laser from an optical assembly to a grating coupler is disclosed. A method for coupling a laser to a photonic integrated circuit is disclosed. The optical assembly includes an optical system disposed on a v-groove bench. The optical system typically includes a laser source, a coupling lens or lens system, an optional isolator, a beam redirector that includes a prism or other light turning element and a cylindrical tube mounted on the v-groove bench. The method of tuning the angle of incidence from the optical assembly to the grating coupler is also disclosed.
