Abstract: Disclosed herein is an optical transmitter for generating a vestigial sideband (VSB) optical signal. The optical transmitter includes: a modulator configured based on a photonic integrated chip (PIC); an optical fiber block; and a lensed thin film filter implemented between the modulator configured based on the PIC and the optical fiber block. The PIC includes at least one grating coupler, and the lensed thin film filter is disposed so that an angle of an optical signal emitted from a first grating coupler of the PIC coincides with an angle of incident (AOI) of the lensed thin film filter to design the first grating coupler and the lensed thin film filter.

Abstract: An optical signal transmission apparatus generates a multi-level optical signal from a multi-level electric signal. The optical signal transmission apparatus detects, based on a supervisory signal generated from an optical signal, an electric-to-optical (E/O) conversion characteristic of an E/O converter configured to convert an electric signal into an optical signal. For example, when the E/O converter generates a multi-level optical signal from a multi-level electric signal based on a bias signal, the optical signal transmission apparatus determines a correspondence relationship between the bias signal and the optical signal. The optical signal transmission apparatus adjusts a use range of intensities of the bias signal based on the determined correspondence relationship so that the E/O converter may linearly operate.

Abstract: An optical multiplexer including an optical waveguide block including a plurality of waveguides for adjusting an optical path of the plurality of optical signals. Optical signals generated in light sources having different wavelengths are input to ports of one side that is an input end of the optical waveguide block, propagated through waveguides connected to the ports, and output to ports of another side that is an output end of the optical wavelength block. Intervals between the waveguides decrease in a direction from the input end to the output end. Intervals between the ports of the input end are smaller than intervals between the ports of the output end. The optical waveguide block has a structure in which at least one layer having at least one waveguide is laminated.
