Abstract :
This paper investigates the linewidth of a hybrid MEMS vertical-cavity surface-emitting lasers (VCSEL) combining an InP-based active component incorporating 7 InGaAlAs quantum wells and a buried tunnel junction (BTJ, Oslash=10 mum) and a concave AlGaAs/GaAs MEMS distributed Bragg reflectors (DBR) with electro-thermal actuation for broadband wavelength tuning up to 60 nm around 1.55 mum.
