| Abstract(in English) | A simulator for GaN intersubband transition optical switches has been developed. Influences of the inhomogeneous broadening and the 2-dimensional mode profile have been taken into consideration. Characteristics of the fabricated switch were limited by a longer absorption peak wavelength and by excess loss due to the dislocations. When they are improved, the switching pulse energy will be reduced to about 10 pJ for ridge waveguides and about 1 pJ for sub-micron high-mesa waveguides. The measured optical gate width (～360 fs) is limited by the widths of the pump pulses, and the intrinsic response time is about 100fs. |
