摘要： An organic-inorganic hybrid nanocomposite thin film for a high-powered and/or broadband photonic device having an organic ligand-coordinated semiconductor quantum dot layer, a photonic device having the same, and a method of fabricating the same are provided. The organic-inorganic hybrid nanocomposite thin film is composed of a stack structure comprising a polymer layer and an organic ligand-coordinated semiconductor quantum dot layer self-assembled on the polymer layer, or composed of a first composite thin film comprising a first polymer layer pattern having a first hole, and an organic ligand-coordinated first semiconductor quantum dot layer pattern filling the first hole. The organic-inorganic hybrid nanocomposite thin film may be formed by spin-coating a semiconductor quantum dot solution and a polymer solution alternately to be stacked by one layer so as to form a multi-layered organic thin film composed of a plurality of layers. The hybrid nanocomposite thin film for a photonic device may be provided by physically coupling a high concentration and broadband semiconductor quantum dot layer and a polymer layer so as to realize a photonic device with high power, broadband, high brightness, and high sensibility, and a flexible photonic device may be also provided.

摘要： Provided is a gain-clamped (GC) optical amplifier using a fiber Raman amplifier (FRA) having a Raman cavity. The FRA having a Raman cavity comprises a Raman fiber module (RFM) amplifying and outputting an input optical signal and a resonant cavity generating a Raman laser and a gain clamping laser (GC laser), wherein the resonant cavity is formed as a feedback loop between an input terminal and an output terminal of the RFM. Accordingly, a gain of an optical signal propagating along a core of RFM keeps a constant value regardless of input signal intensity by generating the GC laser for gain clamping between a wavelength band of the Raman laser and a gain band of input signals.

摘要： Provided is an all-optical gain-clamped fiber amplifier, comprising transmission and isolation means for periodically transmitting an optical signal or reflecting amplified spontaneous emission (ASE) back to a gain medium. The transmission and isolation means can be embodied by an optical interleaver or a number of optical fiber Bragg gratings. Accordingly, an optical signal can be amplified across the entire C-band, and an ASE reflector-based gain-clamped fiber amplifier having a wider dynamic range than conventional amplifiers can be implemented.
