Abstract
Provided are an optical spectrum analyzer and a pulse-modulated light measurement method capable of measuring pulse-modulated light even when a pulse-on time and a pulse period of the pulse-modulated light are unknown. Pulse-modulated light (DUT) is incident on a diffraction grating. A first light receiving unitreceives the 0th-order light of diffracted light diffracted by the diffraction grating. A second light receiving unitreceives diffracted light of an order other than the 0th-order light. A measurement timing signal generation unitgenerates a sampling signal based on the 0th-order light received by the first light receiving unit. The spectrum of the diffracted light received by the second light receiving unit is measured based on the sampling signal generated by the measurement timing signal generation unit.
