A motion-copying system with a symbol-sequence-based phase switch control (SSPSC) scheme is developed for intelligent optical manufacturing. It accomplishes the transfer and reproduction of expert skills with high consistency and adaptability.

Microring resonators have been widely used in passive optical devices such as wavelength division multiplexers, differentiators, and integrators. Research on terahertz (THz) components has been accelerated by these photonics technologies. Compact and...

Differential mode gain equalization arising from different transverse mode profiles within few-mode fiber can be greatly mitigated through controllable femtosecond laser-induced refractive index modulation.

Speckle patterns generated by the intermodal interference of multimode fibers enable accurate broadband wavelength measurements. However, the measurement speed is limited by the frame rate of the camera that captures the patterns. We propose a compac...

Interferometry with computer-generated holograms (CGHs) is a unique solution for the highly accurate testing of large-aperture aspheric mirrors. However, no direct testing method for quantifying the measurement accuracy of CGHs has been developed. In...
