Pure Phase-Modulation mode locking in semiconductor lasers.
Optics letters, 1992Co-Authors: R. Nagar, D. Abraham, Gadi EisensteinAbstract:Pure Phase-Modulation mode locking of an extended-cavity semiconductor laser, operating near 1.5 μm, is demonstrated. The mode-locked laser uses a two-section optical amplifier that provides both gain and Phase Modulation.

Nonlinear spectrum broadening cancellation by sinusoidal Phase Modulation
Optics Letters, 2017Co-Authors: Frederic Audo, Sonia Boscolo, Julien Fatome, Bertrand Kibler, Christophe FinotAbstract:We propose and experimentally demonstrate a new approach to dramatically reduce the spectral broadening induced by self-Phase Modulation occurring in a Kerr medium. By using a temporal sinusoidal Phase Modulation, we efficiently cancel to a large extend the chirp induced by the nonlinear effect. Experimental validation carried out in a passive or amplifying fiber confirm the interest of the technic for the mitigation of spectral expansion of long pulses.

Selecting optical patterns with spatial Phase Modulation.
Optics letters, 1999Co-Authors: Peng-ye Wang, Mark SaffmanAbstract:Optical pattern selection by use of spatial Phase Modulation is investigated experimentally in a photorefractive feedback system. A feedback mirror with spatially periodic Phase Modulation is used for selection of different spatial patterns. Local Phase Modulation is used to create patterns with coexisting spatial symmetries. The experimental results are consistent with numerical simulations based on a model with a cubicly nonlinear medium.

A spatial Phase Modulation laser interferometer
Optics and Lasers in Engineering, 2019Co-Authors: Ke Chen, Zelin Wang, Min Guo, Wang Xiaona, Bowen Liu, Yuming Wang, Yinbo Wang, Senyuan Wang, Jiarong JinAbstract:Abstract We propose and realize a spatial Phase Modulation laser interferometer (SPMLI), which mainly consists of a laser source, an optical fiber, a transparent plate and a linear charge coupled device (CCD). The reflected beams from the upper and lower surfaces of the transparent plate produce two-beam interference. The generated spatial Phase Modulation interference image is taken by the CCD. The spatial frequency of the image is proportional to the wave number of the laser light and the thickness of the transparent plate. Experimental results show that the wavelength and thickness can be measured in picometer-level and nanometer-level resolution, respectively. Compared with other interferometers, the proposed interferometer has the advantages of simple structure, low cost and no need for mechanical scanning components.
