Original Abstract Submitted
The optical circuit of the present disclosure provides a new optical transmitter configuration that achieves both high output and high quality transmission characteristics regardless of variations at cleavage positions. The optical circuit of the present disclosure may be an optical transmitter having an AXEL configuration in which an EADFB laser and a semiconductor optical amplifier (SOA) are integrated. In a window structure portion of a chip emission edge face of the AXEL, a partially thickened bulk semiconductor layer is formed by a structure including a simulated mesa configured to be separated from an optical axis parallel to an optical axis of an emission optical waveguide.
