In this paper, a high-speed tunable filter using optical polarization control module is proposed and experimentally demonstrated. The output spectrum of the filter and is obtained and high-speed tuning performance is demonstrated. The proposed filter is cost effective and simple; consisting of polarization controller (PC), polarizer(P) and polarization maintaining fiber (PMF). To testify the high...
This paper investigates the use of a dual wavelength laser source, a frequency shifter, an erbium-doped fiber amplifier, and an optical filter to compose a multiwavelength fiber laser (MWFL) with an ultranarrow wavelength spacing. The frequency shifter can be achieved by modulating an optical carrier and an electrical sinusoidal signal in an optical single-sideband modulation format. The detuning...
A hybrid fiber-to-the-home (FTTH) and radio-over-fiber (RoF) transport system is proposed to transmit one wired signal and two wireless signals simultaneously through an optical lightwave. By properly utilizing the polarization characteristic of a phase-remodulated and polarization-remodulated optical lightwave, the first- and second-order sidebands of the lightwave can be colorlessly separated for...
This work investigates experimentally the polarization control of InAs-InGaAs quantum dot (QD) semiconductor laser. The polarization characteristic of QD laser at different bias current is studied. The results of this study will be useful in the field of optical signal processing.
This investigation experimentally demonstrates tunable slow light in a 1550 nm distributed feedback Laser. Tunable optical group delays of 30 ps for 10 GHz are achieved by varying the bias current.
