“…This is very important for practical applications in which single pulses are necessary, in the case of multiple pulses it is often the envelope of these pulses that sets the useable pulsewidth. Results on monolithic devices with a passive external cavity [3] showed The ultimate pulsewidths that are attainable from modelocked semiconductor lasers lie in the ten's of femtosecond regime, being limited by the bandwidth of the semiconductor gain material. The shortest measured pulses are an order of magnitude larger than this, due to the effects of dynamic detuning [13].…”

Modelocked semiconductor lasers are a source of subpicosecond pulses at high repetition rates with very low phase noise. This makes them ideal sources for clock/strobe signals for OEIC's and optical computing, for high data rate input devices and for use in optical digital-to-analog converters. These applications will be described in this paper, together with an outline on the state of the art in modelocked semiconductor lasers.

“…Results for monolithically integrated devices [3,4] have produced pulsewidths of 1 .5 -4.0 ps at repetition rates up to 40 0Hz. The availability of such compact and reliable sources of short optical pulses has cleared the way for many practical systems applications of short optical pulses.…”

“…Actively mode-locked lasers can be used to generate picosecond optical pulses at a high repetition rate, and also can be easily synchronized to electrical signals. Several methods have been proposed to generate actively mode-locked pulse trains based on mode-locking in monolithic laser diodes [7], active and hybrid mode-locking of external semiconductor lasers [8], and modelocked solid state lasers [9], respectively. A more promising technique to generate high-repetition-rate pulse trains is the use of actively mode-locked fiber ring lasers with active media in the ring cavity.…”

“…Active modulation is reliable and offers tunability of various parameters, but generates a broad pulsewidth [1] , and also requires bulky and expensive components. Passive modulation, on the other hand, modulates the loss and gain of the laser using saturable absorbers (SAs) [2][3][4][5] or by inducing SA action, such as nonlinear amplifying loop mirrors (NALMs) [6] and nonlinear polarization rotation (NPR) [7,8] .…”

Investigation of ellipticity and pump power in a passively mode-locked fiber laser using the nonlinear polarization rotation technique

An elliptical initial polarization state is essential for generating mode-locked pulses using the nonlinear polarization rotation technique. In this work, the relationship between the ellipticity ranges capable of maintaining mode-locked operation against different pump power levels is investigated. An increasing pump power, in conjunction with minor adjustments to the polarization controller's quarter waveplate, results in a wider ellipticity range that can accommodate mode-locked operation. Other parameters such as noise, pulsewidth, and average output power are also observed to vary as the ellipticity changes.OCIS Over the last few years, fiber lasers have become the key focus in the development of new laser applications due to their significant advantages over their solid state counterparts. The key advantages of fiber lasers include their low weight and compact size, as well as relatively lower losses and ease of alignment. These characteristics make fiber lasers a crucial component of today's optical communication, carrying terabits of information across continents. While fiber lasers can be configured to suit multiple applications, pulsed fiber lasers in particular have recently garnered substantial attention in generating high energy pulses. These pulses serve a variety of applications, including communications, sensing, manufacturing, and medicine. Pulsing in fiber lasers can be achieved by multiple active and passive means, with the most common being Q-switching and mode-locking. Of the two, mode-locking is preferred for applications requiring high frequency pulses but at a lower power.Fiber lasers can be mode locked in three ways; either actively, passively, or as a hybrid of both. Active modulation is reliable and offers tunability of various parameters, but generates a broad pulsewidth [1] , and also requires bulky and expensive components. Passive modulation, on the other hand, modulates the loss and gain of the laser using saturable absorbers (SAs) [2][3][4][5] or by inducing SA action, such as nonlinear amplifying loop mirrors (NALMs) [6] and nonlinear polarization rotation (NPR) [7,8]
