摘要： Provided is a wavelength division multiplexed-passive optical network (WDM-PON) apparatus. The WDM-PON includes an optical source unit, an optical mux, and a chirped Bragg grating. The optical source unit generates an optical signal. The optical mux receives the optical signal from the optical source unit through one end of the optical mux, multiplexes the optical signal, and outputs the multiplexed optical signal. The chirped Bragg grating is connected to the other end of the optical mux. The chirped Bragg grating again reflects the optical signal having passed the optical mux to re-input a certain portion of the optical signal into the optical mux and the optical source unit. The optical mux performs a spectrum slicing on the re-inputted optical signal and operates the optical source unit using a channel wavelength of the optical mux as a main oscillation wavelength.

摘要： Provided is a self-oscillation communication module in which an optical device, a solar battery, and a radio frequency (RF) device are monolithic-integrated. When an active layer of the optical device contains In(Ga)As quantum dots, the optical device can emit light ranging from 800 to 1600 nm and transmit signals at a high speed of 20 Gbps or higher. Since a light absorption layer of the solar battery is formed of InGa(Al)P which has a higher bandgap than silicon and high visible light absorptivity, the solar battery can generate a large current even with a very small light reception area. Therefore, the self-oscillation communication module can always operate using the solar battery without an external power source even in polar regions and deserts and can perform optical communication or high-frequency wireless communication with a wide frequency range.

摘要： An optical amplifier includes a passive waveguide region and an active waveguide region. The passive waveguide region is configured to receive an incident optical signal and adjust a mode of the optical signal. The active waveguide region is integrated to the passive waveguide region and configured to perform gain modulation on the optical signal received from the passive waveguide region by changing density of carriers in response to a current applied to the active waveguide region. Internal loss of the active waveguide region is adjusted to produce a resonance effect and thereby to increase bandwidth of the active waveguide. Therefore, the optical amplifier can have a wide bandwidth under a low-current condition.
