Programmable photonic logic on chips: coupled-cavity (photonic molecule) gates, CMT models, Typer CLI, hardware hooks, and tests for room-temp→quantum.

The lithium niobate thin-film modulator was designed to achieve a modulation frequency of 350 kHz within the 0–2π phase range, further realizing high-speed control of optical field coherence. Credit: ...

A hybrid phase demodulation structure combining a 3 × 3 coupler and Sagnac interferometer is proposed to improve the spatial resolution and phase demodulation performance of the phase-sensitive ...

In this research, we demonstrate an optical frequency comb (OFC) based on a figure-9 laser and polarization-maintaining fibers to measure the dispersion of a microcavity. We adopt a multi-branch ...

Abstract: We have been experimentally demonstrated OTDM-to-WDM conversion from 20 Gb/s to 2×10 Gb/s based on cross-phase modulation in a highly nonlinear fiber. Error-free performance was achieved for ...

Abstract: We report the experimental demonstration of the supercontinuum extended to ultraviolet region of 200-400 nm by the effect of cross phase modulation between the anti-Stokes signal at 400-550 ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
