Abstract :
We present some tuning characteristics of a GaAlAs/GaAs micromachined tunable filter with a thermal strain control layer and heating element integrated on a top surface. We present the design of micromachined filters for a wide tuning range and for fast wavelength tuning. Experimentally, we demonstrate the fast tuning response with rise time and fall time of below 100 μs.
