Effects of current modulation on the amplitude and the frequency of a DFB laser.
Active mode-locking of semiconductor lasers requires modulation of the applied current at a frequency equal to the longitudinal-mode spacing. However,
In this work, we investigated the relationship between the modulation bandwidths and the number of quantum wells of GaN-based blue light-emitting diodes (LEDs). The number of quantum
