    摘要： An optical pickup which appropriately detects reflected light and return light reflected back from an information recording medium even if a laser light B1 emitted from a light source varies in wavelength. The transmittances of a half mirror to the laser light B1 emitted from the light source, and to the reflected light Bwr, Ber or the return light Brr reflected back from the information recording medium are preset according to a predetermined condition, i.e., Tpc(λc)/Tp(λ)=(1−Ts(λ)/(1−Tsc(λc))×(Tsc(λc)/Ts(λ)). Here, λ is a predetermined wavelength emitted from a semiconductor laser as the light source, Ts(λ) is a transmittance to the laser light B1 with a predetermined polarization, Tp(λ) is a transmittance to the reflected light Bwr, Ber or the return light Brr reflected back from the information recording medium when the laser light B1 with the predetermined wavelength λ is emitted, Tsc(λc) is a transmittance to the laser light B1 with a wavelength λc when the semiconductor laser varies in wavelength characteristic, and Tpc(λc) is a transmittance to the reflected light Bwr, Ber or the return light Brr reflected back from the information recording medium when the laser light B1 with the wavelength λc is emitted.

    摘要： An OADM in a wavelength division multiplexing transmission system includes a wavelength selection switch that selects a predetermined wavelength from a multiple optical signal obtained by multiplexing a phase modulated signal and an intensity modulated signal and outputs the selected wavelength signal to a predetermined output port. The wavelength selection switch has a different delay for each wavelength of the multiple optical signal. For example, the wavelength selection switch includes a mirror array. Optical paths from the surfaces of mirrors arranged on the mirror array to the diffraction grating are different in the case of adjacent mirrors.
