Optical microfiber phase modulator directly driven with low-power light

An optical microfiber phase modulator (OMPM) directly driven with low-power light is presented. Phase modulation response of OMPM is theoretically analyzed. A 10-mm optical microfiber (OM), tapered from conventional single-mode fiber, is inserted in one arm of a Michelson fiber interferometer. To drive the OMPM, 980-nm wavelength light with sinusoidal intensity modulation is injected into the inte...
High-Q microwave photonic filter with self-phase modulation spectrum broadening and third-order dispersion compensation

We propose and experimentally demonstrate a scheme of high-Q microwave photonic filter (MPF) using the techniques of self-phase modulation (SPM) spectrum broadening and third-order dispersion (TOD) com-pensation. The optical pulses from a mode-locking laser are spectrally broadened by the SPM in the highly nonlinear fiber. A wideband optical frequency comb with 365 spectral lines within 10-dB powe...
Transforming information from spin encoding to route encoding

Spin (polarization) is widely used in free-space optics, while in photonic integrated circuits (PICs), information is usually encoded in optical route. So a practical way to connect these two encoding methods is necessary for information communication. In this letter, an encoding convertor is designed to connect spin encoding and route encoding. Finite element method is used to calculate the conve...
Editorial for Focus Issue on Optical 3D Display and Imaging

With the impressive progress of flat panel display technologies, the three-dimensional (3D) display and imaging technologies have attracted much attention in recent years as they can provide ultimate realistic views to us. Hence we designed a focus issue intended to introduce recent optical researches in this field, especially the works by some distinguished research groups.This focus issue includ...
