Title:
Wavelength selection optical switch device
Document Type and Number:
Japanese Patent JP6019466
Kind Code:
B2
Abstract:
A wavelength selective optical switch includes an incidence/emergence unit that includes an input port at which signal light made up of light of numerous wavelengths is incident and an output port at which light signals of selected wavelengths are emergent, a wavelength dispersion element that spatially disperses signal light according to a wavelength of the signal light, and synthesizes reflected light, a condenser element that condenses light dispersed by the wavelength dispersion element on a two-dimensional plane, a space phase modulator arranged so as to receive incident light deployed on an xy plane made up of an x-axis direction deployed according to wavelength and a y-axis direction orthogonal to the x-axis direction, and having numerous pixels arranged in a lattice on the xy plane, and a space phase modulator drive unit.
