Dynamic range of wavelength exchange in highly nonlinear dispersion-shifted fiber

We investigate the signal dynamic range of wavelength exchange using 10Gb/s 231-1 PRBS. Data exchanging between two wavelengths is achieved with signal dynamic range ∼20dB. Bit-error-rate of <10-9 is maintained with power penalties of <2dB. © 2008 Optical Society of America.published_or_final_versio

A simple 10-GHz picosecond pulse source based on fiber optical parametric oscillator

We demonstrate a simple fully fiber-integrated picosecond optical parametric oscillator based on high-nonlinear dispersion-shifted fiber. High quality picosecond pulses are generated with a 40-nm tuning range. © 2009 IEEE.published_or_final_versio

Picosecond fiber optical parametric oscillator with 500 nm tuning range using dispersion-shifted fiber

We demonstrate a picosecond fiber optical parametric oscillator with a tuning range of 500 nm pumped by a relatively low-cost intensity-modulated pump. Pulses with pulsewidth from 7 ps to 17 ps are generated. © 2010 Optical Society of America.published_or_final_versionThe 2010 Conference on Optical Fiber Communication (OFC), collocated National Fiber Optic Engineers Conference (OFC/NFOEC), San Diego, CA., 21-25 March 2010.

Fast swept-source generation based on fiber optical parametric amplifier

We experimentally demonstrate a fast frequency swept-source using the dispersive Fourier transformation-based fiber optical parametric amplifier. The swept rate is as high as 78 MHz, with a linewidth of 0.135 nm. © 2011 OSA.published_or_final_versio

Widely tunable picosecond optical parametric oscillator using highly nonlinear fiber

We demonstrated a fully fiber-integrated widely tunable picosecond optical parametric oscillator based on highly nonlinear fiber. The ring cavity with a 50 m highly nonlinear fiber was synchronously pumped with a picosecond mode-locked fiber laser. The tuning range was from 1413 to 1543 nm and from 1573 to 1695 nm, which was as wide as 250 nm. A high-quality pulse was generated with a pulse width narrower than that of the pump. © 2009 Optical Society of America.published_or_final_versio

Wavelength-tunable nearly-transform-limited pulse generation based on fiber optical parametric oscillator

Paper P1.02We demonstrate an all-fiber widely-tunable sub-picosecond fiber optical parametric oscillator based on highly-nonlinear dispersion-shifted fiber. Nearly-transform-limited sub-picosecond pulses are generated over a 60-nm tuning range around 1550 nm. © VDE VERLAG GMBH.published_or_final_versio
