Preface Since the first edition of this book in 1997, the photonics landscape has evolved considerably and so has the role of DFB laser diodes. Although tunable laser diodes are introduced ever more in
Thorlabs'' DFB13TK Turnkey, Low-Noise Distributed Feedback (DFB) Laser System is a ready-to-use laser system that integrates a 1310 nm DFB laser with a low
In a DFB laser, the grating and the reflection is generally continuous along the cavity, instead of just being at the two ends. This changes the modal behavior considerably and makes the laser more stable.
