An optical spectrum analyzer is provided that can separate measurement target light into orthogonal polarization components and perform measurement and enable optical spectrum measurement that does not depend on polarization of the measurement target light. Measurement target light is separated into two orthogonal polarization components, the two polarization components whose position is shifted in an engraved line direction of a diffraction grating are incident on the diffraction grating, diffracted light of the two polarization components emitted from the diffraction grating is condensed, and the condensed diffracted light is incident on an incident side end surface of a 2-core ferrule with the two polarization components adjacent to each other.
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 3. A first light receiving unit 8 receives the 0th-order light of diffracted light diffracted by the diffraction grating 3. A second light receiving unit 7 receives diffracted light of an order other than the 0th-order light. A measurement timing signal generation unit 9 generates 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.
