Abstract :
A tunable fibre-extended-cavity laser is demonstrated consisting of an InGaAsP superluminescent diode, a single-mode fibre with an integral microlens and a variable-period diffraction grating coupled to the fibre. A tuning range of 450 Ã… has been observed, limited by the gain spectrum of the gain medium.
