Latest Patents

One of Nakamura's latest patents is an external cavity resonator type tunable light source that can be easily manufactured and is capable of wavelength sweeping at high speed. This invention utilizes a collimator lens to convert light beams emitted from a low reflectance facet of a semiconductor laser into parallel light beams. A diffraction grating receives and diffracts these light beams at a predetermined incident position and angle of a diffraction face. Additionally, a turnable mirror is positioned opposite the diffraction facet of the grating, allowing the diffracted light beams to be incident in a reverse optical path to the diffraction face, thus returning the incident light beams to the laser. A stationary mirror further enhances the system by directing the light beams from the collimator lens to the diffraction grating.
