A novel spot size converter is proposed and investigated for low-loss edge coupling of a multimode LD, which has high output power, to an optical integrated circuit. The spot size converter of an inverted tapered comb structure has been designed to couple a LD with a near-field profile of 0.8 microns in the vertical direction into a dielectric glass waveguide with a mode field size of 0.13 microns. The coupling efficiency was simulated using the beam propagation method and estimated to be –0.02dB.
