    Abstract: A wavelength tunable laser diode using a double coupled ring resonator is provided. A new double coupled ring resonator structure is formed by a connection of two ring resonators having different radii so that stable laser oscillation occurs only in a resonant wavelength at which the two ring resonators are simultaneously resonated, and the effective refractive index of the two ring resonators is properly controlled differently for tunable laser oscillation wavelengths. The reproducibility of the optical coupling characteristics of the passive waveguides and the ring resonator can be assured by multi-mode couplers. This results in improved manufacturing productivity of the wavelength tunable laser diode. It is possible to amplify and output an output light without having an effect on oscillation wavelength characteristic by means of an optical amplifier integrated in an output end.

    Abstract: Provided is a frequency-tunable terahertz light source device. The frequency-tunable terahertz light source device satisfies a Littrow diffraction condition at a wavelength and simultaneously satisfies a Littman-Metcalf diffraction condition at another wavelength using a double diffraction grating having two grating periods. Thus, oscillations simultaneously occur at the two different wavelengths, such that a terahertz wave can be stably generated by beating of the two oscillation wavelengths. In addition, the frequency-tunable terahertz light source device can readily change a frequency up to several terahertz and can be fabricated in a small size.

    Abstract: Disclosed is a transmitter optical module which includes an electro-absorption modulated laser modulating a light into an optical signal through a high-frequency electrical signal; a first sub-mount transferring the high-frequency signal to the electro-absorption modulated laser; and a second sub-mount receiving the high-frequency signal from the electro-absorption modulated laser to terminate the electro-absorption modulated laser. A length of a first wire connecting the first sub-mount and the electro-absorption modulated laser is different from a length of a second wire connecting the second sub-mount and the electro-absorption modulated laser.
