Abstract(in English) | An intersubband optical amplifier with a GaN/A1N coupled quantum well structure powered both by current injection and by optical pumping has been proposed as an ultrafast all-optical switch which has the advantages of ultrafast response (~Tb/s) of the intersubband transition in GaN and low switching power of semiconductor optical amplifiers. A rate equation analysis predicted that a signal gain of about 20 dB is achievable at 1-W cw optical pumping, and that ultrafast optical gate operation with an extinction ratio of more than 10 dB will be realized with a control light power of less than 10 dBm, which is two orders of magnitude smaller than that in saturable absorber-type intersubband transition optical switches. |
