We present MEMS tunable Gires-Tournois interferometers (GTIs) based on deeply etched Bragg reflectors. The broad reflection bandwidth (~100 nm) of the Bragg reflectors allows operation over almost the whole C and L bands with a single cavity, while the in-plane configuration allows the design of a wide range of cavity length (i.e. free spectral range). Applications such as fast tunable dispersion compensation in optical fiber networks are expected.
