WAVELENGTH TUNABLE EXTERNAL RESONATOR LASER USING OPTICAL DEFLECTOR |
摘要 |
The present invention relates to an optical deflector driven by an electrical signal, and a wavelength unable external resonator using the same . The optical deflector of a triangle shape; capable of controlling the refractive index of a beam depending on the electrical signal, is positioned between a reflection mirror and a diffraction grating in a Littman-Metcalf mode extern al resonator or between a lens and the diffraction grating in a Littrow mode external resonator. Thus, even with the reflection mirror and the diffractin g grating fixed, the refractive index of the beam generated from a laser diode can be controlled by adjusting the electrical signal applied to the optical deflector; so that beam having a specific wavelength can be focused and the wavelength can be rapidly and consecutively tuned.
