Fig. 3. From: 115 kHz tuning repetition rate ultrahigh-speed wavelength-swept semiconductor laser.

(a) Oscilloscope trace of the laser output, showing four tuning cycles at a repetition rate of 115 kHz. (b) Integrated laser output spectrum. Solid black curve, laser output with the proposed polygon-scanning filter of Fig. 1(c) for a 115 kHz tuning repetition rate. Gray curve, laser output with the previous filter design7 using the same optical components. Dashed curve, laser output with the filter design of Fig. 1(a) using the same optical components.
