Original Abstract Submitted

provided is a continuous frequency-tuning array light source. the light source may include a substrate including a gain region, a phase modulation region, and an internal reflection region arranged in a first direction, a core layer extending in the first direction on the substrate and including a grating in the internal reflection region, an upper clad layer on the core layer and the substrate, external reflection coating on one side wall of the substrate adjacent to the gain region, the core layer, and the upper clad layer, a dielectric layer on the upper clad layer in the phase modulation region and the internal reflection region, an ohmic contact layer on the upper clad layer in the gain region, and electrodes on the dielectric layer and the ohmic contact layer.
