| he integration of ;Firstly, using picosecond spectroscopy, I temporally- and spectrally-resolved the formation (optical turn-on time) of the changes in absorption coefficient in hetero n-i-p-i's. The optical turn-on time is determined by the time for the carriers to escape the wells ;I then used all of my experimental results to design an interdigitated hetero n-i-p-i optical modulator with a contrast ratio of 3.5:1, an operating voltage of 2 V, a maximum operating frequency of 1GHz and an optical throughput of... |
