    摘要： Provided is a tunable waveguide Bragg grating device, which includes: a waveguide through which incident light can travel; a Bragg grating formed in at least one region of the waveguide; and at least one thermal tuning unit formed at a position displaced from the central line of a waveguide core along the length direction of the waveguide core. Accordingly, it is possible to tune a reflection wavelength band and a group delay characteristic of the waveguide Bragg grating device in a variety of ways. It is also possible to manufacture a multiple channel tunable waveguide Bragg grating device with ease by applying an array arrangement, which is advantageous in constructing an integrated optical module.

    摘要： Provided is a method for determining the optimal resonant length, among a large number of local resonant lengths which satisfy a resonant condition, that maximizes wave intensity in a resonant structure. In the second harmonic generation or the cascaded difference frequency generation device using the resonant structure by which the second harmonic wave of a pump wave resonates, the optimal resonant length is determined so that the intensity of an optical wave is maximized. The intensity distribution of the optical wave is defined, according to the resonant feedback condition or the no-resonant feedback condition, as a function of the resonant lengths to determine the optimal resonant length.

    摘要： Provided is a resonant cascaded difference frequency generator that is capable of improving the conversion efficiency of the second-order nonlinear optical phenomena by resonating the second harmonic wave of a pump light. The resonant cascaded difference frequency generator includes: a nonlinear medium, which receives a pump light and a signal light and then generates the second harmonic wave of the pump light through second harmonic generation, in a cascaded way generates a converted light of a difference frequency through difference frequency generation between the signal light and the second harmonic wave; and a resonant structure that resonates the second harmonic wave of the pump light on the basis of the nonlinear medium.
