Paper Abstract

We report here micro-transmission measurements of a highly selective and a widely tunable optical filter at 1.55 micrometers . This filter is formed by a (lambda) /2 air cavity sandwiched between two 3.5 alternances InP-air Bragg mirrors. Reflectors and air cavity are fabricated by selective micro- machining of InGaAs sacrificial layers. Measurements have shown a very large wavelength tuning of 108nm for only 4.7V and a filter linewidth of 0.6 nm. Such performances have been possible because of the high reflectivity, large bandwidth and good optical confinement of the InP-air Bragg mirrors.
