13.2 Distributed Feedback (DFB) Lasers (1D Photonic Crystal Lasers) 13.2.1 Introduction: The structure of a DFB laser is shown in the Figures below. The laser cavity is not like any we have seen before.
Distributed feedback lasers are diode or fiber lasers where the whole laser resonator consists of a periodic structure, in which Bragg reflection occurs.
We demonstrate an over 500 mW (at 45°C) operation of 1.3 μm SOA-integrated DFB laser with reduced thermal resistance. The device exhibits single-mode operation with SMSR of over 50dB and narrow
