Paper Abstract

We propose and demonstrate a highly linear-polarized hybrid integrated external cavity laser (ECL) on a planar lightwave circuit (PLC). An in-PLC polarizer is designed to improve polarization extinction ratio (PER). The in-PLC polarizer based on a 45°-tilted grating was simply formed in the laser cavity composed of a Fabry-Perot laser diode and a Bragg grating. The proposed ECL exhibited singled longitudinal mode oscillation with polarization extinction ratio of 30dB.
