Phase-shifting laser diode interferometer using pulse modulation

Applied Optics, 2012
A phase-shifting laser diode interferometer that uses direct pulse modulation is proposed and demonstrated. We found that a laser beam with a wide range of wavelength variation at constant optical power could be generated when a pulsed current was injected into the laser diode.

Phase shifting mask modulated laser patterning on graphene

Nanotechnology, 2016
A one-step graphene patterning method is developed in this paper. A phase shifting mask is used to modulate incident laser beam spatially and generate graphene patterns by laser heating. Periodic graphene nanoribbon and nanomesh structures are fabricated by employing 1D and 2D phase shifting masks, respectively.

A Full-Power-Range Optimization Scheme Under Double-Side Asymmetrical Phase-Shift Modulation in DAB-Based Distributed Energy Storage System

IEEE Journal of Emerging and Selected Topics in Power Electronics
For distributed energy storage systems, dual-active-bridge (DAB) is often employed as an interface among photovoltaic (PV) port, storage system, and load. Efficient DAB operation will be beneficial to energy conversion efficiency.

New phase shift modulator for resonant converters

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
Resonant converters are important in the search for high efficiency energy use and low electromagnetic interference (EMI). In this paper, nonlinarities of the traditional phase shift modulator (PSM) application to resonant converters are addressed. A new modulator topology, suited for resonant converters, is proposed.

Corrugation-pitch-modulated phase-shifted DFB laser

IEEE Photonics Technology Letters, 1989
A corrugation-pitch-modulated phase-shifted distributed feedback (DFB) laser is proposed to reduce the spatial-hole-burning effect along the laser cavity. The structure of the proposed corrugation-pitch-modulated phase-shifted DFB laser is illustrated.
