“…The operating wavelength is mainly determined by the EDF gain and cavity loss in the cavity whereby the comb like peaks in the MKR compete to lase. The peak laser has a signal to noise ratio of about 33.7 dB, which is comparable with other works [12,15]. Inset of Fig.…”

“…Recently, single frequency Erbium doped fiber lasers (EDFLs) have been shown to be capable of providing mode hop free lasers in the form of distributed feed back (DFB), distributed Bragg reflector (DBR) and ring lasers [8][9][10][11][12][13][14][15]. Many works have also been reported on Q switched and mode locked fiber lasers [16][17][18].…”

A tunable laser is demonstrated using a microfiber knot resonator structure made by erbium doped fiber (EDF). The laser is made of a 2 m long EDF where 30 mm of its end section is tapered to con struct a microfiber knot resonator (MKR). The combination of the EDF and MKR generates a stable single wavelength laser at 1555 nm wavelength with a signal to noise ratio (SNR) of 33.7 dB using a 63 mW of 980 nm pump power. The peak wavelength of the laser can be tuned by 340 pm as the MKR diameter reduces from 5.0 to 0.5 mm with an acceptable penalty in output power.

“…And the wavelength separation of dual wavelength mode locked pulses can be tuned between 2.38 and 20.45 nm. Arrayed waveguide grating (AWG) could also be used to provide tunability, where the tuning ranges of 9.92 and 11.9 nm are realized, respectively [14,15]. Except these, the mode locked wavelength tunable fiber ring laser was also realized based on the nonlinear effect [16].…”

Tunable filter based on a pair of special long-period fiber gratings and its application in fiber ring laser

et al. 2012

View full text Add to dashboard Cite

A filter based on a Mach-Zehnder interferometer (MZI) formed by cascading a pair of long period fiber gratings (LPFGs) written by CO 2 laser in a twisted single mode fiber is proposed. The transmis sion spectrum of the filter is tuned by modifying the bending curvature of the MZI, and thus wavelength tun ing is achieved. And a tunable erbium doped fiber (EDF) ring laser employing the filter as a wavelength selection component is experimentally demonstrated. The laser can be tuned continuously from 1573.05 to 1595.75 nm with a side mode suppression ration of ~50 dB over the total tuning range.

“…In particular, there is active research into SWFLs that use arrayed waveguide gratings (AWGs), including a tunable fiber laser generated in the O band that was developed using semiconductor optical amplifiers (SOAs) [4], a quad wavelength fiber laser that simulta neously generates dual wavelength outputs in the O and C band regions via an SOA [5], a linear cavity dual wavelength fiber laser in the C band using EDF [6], and a high power tunable fiber laser in a C band using EDF [7]. 1 The article is published in the original.…”

This paper proposes a switchable wavelength fiber laser (SWFL) based on an arrayed waveguide grating (AWG) and a gain saturated reflective semiconductor optical amplifier (RSOA). The SWFL was experimentally implemented in the C and L bands. In order to achieve narrow linewidth oscillation, the SWFL was driven by bidirectional injection locked RSOAs. The RSOA was operated in the gain saturated region, using gain compression properties to obtain uniform power over a wide bandwidth. Based on this con figuration, we obtained 40 C band international telecommunication unit (ITU) wavelengths with 100 GHz channel spacing. The SWFL displayed a narrow 3 dB bandwidth (<0.06 nm), a high and uniform peak power (P max > 0.22 dB, ΔP max < 0.26 dB), and a high and uniform side mode suppression ratio (SMSR > 66 dB, ΔSMSR < 1 dB). The peak power and wavelength stabilities were ±0.24 dB and ±0.01 nm, respectively, at room temperature over a 1 h period.
