Light modulation device and filter device |
摘要 |
A light modulation device comprises: a magnetic garnet single crystal having a main surface and an easy magnetization axis in parallel with the main surface; an optical source arranged such that light emitted from the optical source is introduced into the magnetic garnet single crystal and propagates in the magnetic garnet single crystal along a first direction on the main surface; and one or a pair of transducers provided on the main surface of the magnetic garnet single crystal for applying a microwave signal in a region of the magnetic garnet single crystal where the light from the optical source propagates, to modulate the light.
