© 2020 Optical Society of America.In this work, we demonstrate a single frequency, high power fiber-laser system, operating at 1550 nm, generating controllable rectangular-shape μs pulses. In order to control the amplified spontaneous emission content, and overcome the undesirable pulse steepening during the amplification, a new method with two seed sources operating at 1550 nm and 1560 nm are used in this system. The output power is about 35 W in CW mode, and the peak power is around 32 W in the pulsed mode. The repetition rate of the system is tunable between 50 Hz to 10 kHz, and the pulse duration is adjustable from 10 μs to 100 μs, with all on the fly electronically configurable design. The system demonstrates excellent long and short time stability, as well as spectral and spatial beam quality.

High power microsecond fiber laser at 1.5 mu m Pavlova, Svitlana; Yagci, M. Emre; Eken, S. Koray; Tunckol, Ersan; Pavlov, Ihor (The Optical Society, 2020-06-01) In this work, we demonstrate a single frequency, high power fiber-laser system, operating at 1550 nm, generating controllable rectangular-shape mu s pulses. In order to control the amplified spontaneous emission content, and overcome the undesirable pulse steepening during the amplification, a new method with two seed sources operating at 1550 nm and 1560 nm are used in this system. The output power is about 35 W in CW mode, and the peak power is around 32 W in the pulsed mode. The repetition rate of the sy...
Performance of M-ary pulse position modulation for aeronautical uplink communications in an atmospheric turbulent medium Ata, Yalcin; Baykal, Yahya; Gokce, Muhsin Caner (The Optical Society, 2019-10-01) This paper discusses the bit-error-rate (BER) performance of an aeronautical uplink optical wireless communication system (OWCS) when a Gaussian beam is employed and the M-ary pulse position modulation technique is used in an atmospheric turbulent medium. Weak turbulence conditions and log-normal distribution are utilized. The Gaussian beam is assumed to propagate on a slant path, the transmitter being ground-based, and the airborne receiver is on-axis positioned. Variations of BER are obtained against the ...
High responsivity InP-InGaAs quantum-well infrared photodetectors: Characteristics and focal plane array performance Cellek, OO; Ozer, S; Beşikci, Cengiz (Institute of Electrical and Electronics Engineers (IEEE), 2005-07-01) We report the detailed characteristics of long-wavelength infrared InP-In0.53Ga0.47As quantum-well infrared photodetectors (QWIPs) and 640 x 512 focal plane array (FPA) grown by molecular beam epitaxy. For reliable assessment of the detector performance, characterization was performed on test detectors of the same size and structure with the FPA pixels. Al0.27Ga0.73As-GaAs QWIPs with similar spectral response (lambda(p) = similar to 7.8 mu m) were also fabricated and characterized for comparison. InP-InGaAs...
Efficient computation of 2D point-spread functions for diffractive lenses Ayazgok, Suleyman; Öktem, Sevinç Figen (The Optical Society, 2020-01-10) Diffractive lenses, such as Fresnel zone plates, photon sieves, and their modified versions, have been of significant recent interest in high-resolution imaging applications. As the advent of diffractive lens systems with different configurations expands, the fast and accurate simulation of these systems becomes crucial for both the design and image reconstruction tasks. Here we present a fast and accurate method for computing the 2D point-spread function (PSF) of an arbitrary diffractive lens. The method i...
High Conversion Efficiency InP/InGaAs Strained Quantum Well Infrared Photodetector Focal Plane Array With 9.7 mu m Cut-Off for High-Speed Thermal Imaging Eker, Suleyman Umut; Arslan, Yetkin; Onuk, Ahmet Emre; Beşikci, Cengiz (Institute of Electrical and Electronics Engineers (IEEE), 2010-02-01) InP/InGaAs material system is an alternative to AlGaAs/GaAs for long wavelength quantum well infrared photodetectors (QWIPs). We demonstrate a large format (640 x 512) QWIP focal plane array (FPA) constructed with the strained InP/InGaAs material system. The strain introduced to the structure through utilization of In0.48Ga0.52As (instead of In0.53Ga0.47As) as the quantum well material shifts the cut-off wavelength from similar to 8.5 to 9.7 mu m. The FPA fabricated with the 40-well epilayer structure yield...
