Abstract

We investigate the optical feedback sensitivity of GaAs-based quantum dot (QD) distributed-feedback (DFB) diode lasers, which has demonstrated an isolator-free operation under a reflection of up to -16dB. This strong tolerance against the optical feedback suggests the high potential of isolator-free operation in photonic integrated circuits.
