The paper presents a thermo-optic tunable laser that makes use of a micromachined etalon to form the external cavity. The wavelength tuning is obtained by the thermo-optic effect of the silicon material. In experiment, a wavelength tuning range of 14 nm is demonstrated by applying a heating current of 18.7 mA to a deep-etched silicon etalon of 206 mum wide. In the dynamic test, this laser measures...
This paper presents an optical logic NOR gate constructed by two MEMS tunable lasers and a Fabry-Perot (FP) laser chip. The key idea is that the FP chip is directly controlled by two tunable optical signals via the physical mechanism of injection locking. Compared with other fiber-based gating mechanisms, this logic operation only depends on the optical power without need for accurate phase matching...
This paper presents a tuning mechanism to provide an adjustable virtual pivot for MEMS tunable lasers, which eliminates the mode hopping problem associated with conventional Littrow lasers. The key idea is to attach the two ends of the blazed grating to two separate translational actuators. The relative displacements of the actuators can be used to translate and/or rotate the blazed grating in a controllable...
