The active switched capacitor integrated quadratic boost converter is a propitious alternate to … Gain-switching is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, of the order of picoseconds (10 s). In a semiconductor laser, the optical pulses are generated by injecting many carriers (electrons) into the active region of the device, bringing the carrier density within that region from below to above the lasing threshold. When the carrier density exceeds that value, the ensuing stimulated …
