Abstract(in English) | ISBT in GaN/AlN MQW has been expected to be a ultra fast all-optical switch Now, a scheme of inducing ISBT, whose wavelength of 155 μm, by IBT is investigated. This scheme gives us the applications for #1 ON-OFF controlling of ISBT devices by IBT resonant light, #2 hi-speed ultraviolet detector The latter device is expected to show hi-speed detection is same as IBT relaxation time For realization of those devices, we investigated the IBT excitation dependences of intersubband absorption As the result, a relatively high ISBT extinction ratio of 38 % at IBT excitation power of 3 mW was obtained, and also ISBT extinction ratio of over 99 % at 40 mW by a calculation These results show the possibilities of realization for those devices |
