“…ErYb codoped fiber based power amplifiers are the most mature and efficient fiber technology for achieving high average and peak powers at 1.5µm. Results presented in this paper are an order magnitude larger in average power than previously reported, multi Channel WDM high power demonstration [10][11][12] , furthermore PPM format requires >100x higher peak powers compared to previously reported OOK modulation formats.…”

Fibertek is developing a power efficient, space qualifiable Eight WDM Channel PPM Downlink Tx Seed LAser Module (SAM) with TDM based FWM Mitigation Capability. SAM will be compatible with space qualifiable, high TRL, 8 WDM channel, 50W WDM Amplifier prototype that was delivered in early 2021. SAM together with the WDM Amplifier will meet all the requirements of a spaceflight DSOC WDM Transmitter. Fibertek has developed a comprehensive multi gain stage 1.5um WDM fiber amplifier numerical model that accurately quantifies the degradation of WDM PPM signals due to FWM. The physics model is used to quantify FWM-PEV for all 2 and 3 overlapping wavelength configurations of PPM orders 256-16. Results are used as inputs to a PPM statistics model that calculates the PEV statistics for all the PPM orders and WDM channels. The significant Improvements of the PEV statistics with the TDM based FWM mitigation using 2 or 3 wavelength subslots are quantified.

“…The commercial SOAs being used herein are widely available (ModelISPAD1501, InPhenix) with 25 ps carrier recovery time [55]. The signal laser sources, which are used to generate and control the peak power of the input signals, can be practically supplied by Erbium Ytterbium-Doped Fiber Amplifiers, which are commercially available and designed to exhibit high output power [56].…”

We theoretically analyze the performance of all-optical multifunctional AND, NOT-OR (NOR), and exclusive-NOR (XNOR) logic gates at 80 Gb s−1 using return-to-zero data format in a compact scheme based on semiconductor optical amplifiers (SOAs). The AND logic gate is formed by incorporating two SOAs in a Mach–Zehnder interferometer and the NOR logic gate is formed using a single SOA followed by a series delayed interferometer. Then an additional logic gate, XNOR, is realized by by the combination of the AND and NOR output logic channels. Therefore, three logic operations are performed using a compact scheme within few resources. The quality factor (QF) of the considered Boolean functions against the key operational parameters of the input data and SOA is examined, considering the effects of the amplified spontaneous emission, operating temperature, and phase noise for more realistic results. The results of Wolfram Mathematica show that three logic functions, AND, NOR, and XNOR, can simultaneously be realized at 80 Gb s−1 using the employed compact scheme with high QF.

“…From a fabrication point of view, this adds tolerance by the DFWM process to a target microwire diameter. And from an application point of view, the bandwidth and gain of the DFWM device compare well with those of commercial fiber amplifiers doped with erbium and/or ytterbium [33]. In each of the conversion efficiency spectra, the impact of Raman scattering is also observed, appearing in the form of gain (loss) at a Stokes (anti-Stokes) wavelength shift of 7 THz or ~53 nm at 1550 nm with respect to the pump wavelength.…”

Abstract:We present polymer (PMMA) cladded chalcogenide (As 2 Se 3 ) hybrid microwires that realize optical parametric four-wave mixing (FWM) with wavelength conversion bandwidth as broad as 190 nm and efficiency as high as 21 dB at peak input power levels as low as 70 mW. This represents 3-30 x increase in bandwidth and 30-50 dB improvement in conversion efficiency over previous demonstrations in tapered and microstructured chalcogenide fibers with the results agreeing well with the simulations. These properties, combined with small foot-print (10 cm length), low loss (<4 dB), ease of fabrication, and the transparency of As 2 Se 3 from near-to-mid-infrared regions make this device a promising building block for lasers, optical instrumentation and optical communication devices.References and links
