Monolithically Integrated QCSE-tuned InGaAsP MQW ridge waveguide DBR laser

摘要

The first QCSE-tuned ridge waveguide InGaAsP MQW DBR laser monolithically integrated with QW-intermixed tuning sections is demonstrated. QCSE is used for tuning with minimal thermal effects over ～7nm for <2.5V applied voltage change.
