Abstract :
We have demonstrated ultrasmall buried heterostructure photonic crystal lasers. Very low threshold optical power in butt-jointed InP waveguide of 1.5 μW and maximum fiber output of 0.44 μW are achieved. High-speed direct modulation (3-dB modulation bandwidth of 5.5 GHz) is also demonstrated at room temperature by optical pumping.
