Patent ID: 8098422

Claim:
A wavelength conversion device package comprises: an optical oscillator comprising a light source that emits light; a flexible optical transmitter that transfers the light emitted from the optical oscillator to a wavelength modulator; and wherein the wavelength modulator receives the light from the optical transmitter and radiates a wavelength-modulated light, and wherein the optical oscillator further comprises: a temperature sensor that measures a temperature of the light source; a first mount block that supports the light source and the temperature sensor; and a temperature regulator formed under the first mount block, that regulates a temperature of the light source, based on the temperature measured by the temperature sensor, wherein the optical oscillator comprises: a heat radiating block that is disposed between the first mount block and the temperature regulator, that supports the first mount block and that radiates a heat generated by the light source to outside; and a fixing part formed on the heat radiating block, that fixes the optical transmitter; wherein the wavelength modulator comprises: an optical waveguide that receives the light from the optical transmitter and that modulates a wavelength; and an angle polishing block that is formed at one end of the optical waveguide, that secures the optical transmitter and that optically aligns the light from the optical transmitter with the optical waveguide.
