a Temporal profile and b optical spectrum of the frequency-chirped optical pulse from the FDML laser when the bias voltage VPP applied to the micro-heater is 830 mV. The optical spectrum of the frequency-chirped optical pulse from the FDML when the bias voltages VPP applied to the micro-heater are c 350 mV, d 550 mV, and e 1040 mV.
