Tunable multi-wavelength fiber lasers based on an Opto-VLSI processor and optical amplifiers

Abstract

A multi-wavelength tunable fiber laser based on the use of an Opto-VLSI processor in conjunction with different optical amplifiers is proposed and experimentally demonstrated. The Opto-VLSI processor can simultaneously select any part of the gain spectrum from each optical amplifier into its associated fiber ring, leading to a multiport tunable fiber laser source. We experimentally demonstrate a 3-port tunable fiber laser source, where each output wavelength of each port can independently be tuned within the C-band with a wavelength step of about 0.05nm. Experimental results demonstrate a laser linewidth as narrow as 0.05 nm and an optical side-mode-suppression-ratio (SMSR) of about 35 dB. The demonstrated three fiber lasers have excellent stability at room temperature and output power uniformity less than 0.5 dB over the whole C-band. , 1298-1299 (1996). 5. A. Bellemare, M.

Opto-VLSI-based tunable photonic RF filter

“…An Opto-VLSI processor is a liquid crystal (LC) cell array controlled by a Very-LargeScale-Integrated (VLSI) circuit below the LC layer (Xiao et al 2009). It is driven by digital holographic diffraction gratings capable of steering/shaping incident optical beams as illustrated in Fig.…”

Tunable polarization-maintaining single-mode fiber laser based on a MEMS processor

“…Compared to tunable semiconductor lasers, fiber lasers have advantages of narrow linewidth, low intensity noise, high output power, and inherent compatibility with fiber optics. Up to now, there are several approaches to realize single-mode tunable fiber laser, including the use of fiber Bragg grating (FBGs) [1,2] , acousto-optic tunable filter [3,4] , Fabry-Perot filter [5,6] and Opto-VLSI processor [7,8] etc.…”

Tunable multi-wavelength SOA based linear cavity fiber laser source for optical communications applications

“…These include linear cavities [7], ring cavities [8][9], compound fiber ring cavities [10], and Fox-Smith cavities [11]. The wavelength selectivity can be achieved by inserting various wavelength selective elements in the cavity, such as an Opto-VLSI processor [12], a FabryPerot etalon [13], fiber comb filters [14] or an interferometer filter [15]. A superimposed chirped fiber Bragg grating (CFBG) or a polarization-maintaining fiber (PMF) in a ring cavity [16,17] are also alternative wavelength-selective components that are commonly used in the implementation of fiber lasers.…”
