Abstract
A curved waveguide, strained multiple quantum well reflective amplifier with an integrated front facet mode expander has been designed and fabricated. A device without facet coatings has been found to have a chip gain of 36 dB with 6 dB of gain ripple. This equates to an effective facet reflectivity of 8×10-6
