    Abstract: Provided is an optical comb generator including a light source, a first waveguide region, a modulation region, and a second waveguide region. The light source is configured to output single-mode light. The first waveguide region divides an output of the light source into first light and second light. The modulation region includes a first modulator and a second modulator modulating the first light and the second light respectively. The second waveguide region combines outputs of the first modulator and the second modulator to output an optical comb. Here, the first modulator and the second modulator respectively include a first quantum well and a second quantum well having an asymmetric structure with respect to each other. The light source, the first waveguide region, the modulation region, and the second waveguide region are integrated into one substrate.

    Abstract: Provided are a laser diode generating passive mode locking that does not contain non-linear sector of an SA, and a method of creating an optical pulse using the same diode. The laser diode includes a DFB sector serving as a reflector and a gain sector. The gain sector is connected to the DFB sector and includes an as-cleaved facet formed at the end of the gain sector. When a current less than a threshold current is applied to the DFB sector to allow the DFB sector to operate as a reflector, passive mode locking occurs swiftly and therefore a sector of the SA is not required, which makes manufacturing simple. Also, it is possible to effectively extend a frequency variable region compared to using of the SA.

    Abstract: A high-efficiency laser diode is provided. Since a λ/4 phase-shifted distributed feedback (DFB) laser diode has a great coupling coefficient, mode stability is poor due to spatial hole burning when multiplication of the coupling coefficient by length of a resonator is equal to or greater than 2. In the inventive concept, a region capable of controlling spatial hole burning is inserted into a semiconductor laser diode structure. Thus, an ultrahigh-speed pulse laser diode having a repetition rate in the band ranging from 100 GHz to 300 GHz is obtained. In addition, a single-mode laser diode with improved energy use efficiency is implemented by changing the configuration of a laser diode.
