In this article, we propose a large bandwidth mode-order converter design by dielectric waveguides with equal lengths but different cross-sectional areas. The efficient conversion between even and odd modes is verified by inducing required phase difference between the equal length waveguides of different widths. Y-junctions are composed of both tapered mode splitter and combiner to connect mono-mode waveguide to multi-mode waveguide. The converted mode profiles at the output port show that the device operates successfully at designed wavelengths with wide bandwidth. This study provides a novel technique to implement compact mode order converters and direction selective/sensitive photonic structures. (C)2015 Optical Society of America

High power microsecond fiber laser at 1.5 μm Pavlova, Svitlana; Yagci, M. Emre; Eken, S. Koray; Tunckol, Ersan; Pavlov, Ihor (The Optical Society, 2020-06-08) © 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 mod...
Effective bandwidth approach for the spectral splitting of solar spectrum using diffractive optical elements Yolalmaz, Alim; Yüce, Emre (The Optical Society, 2020-04-27) Spectral splitting of the sunlight using diffractive optical elements (DOEs) is an effective method to increase the efficiency of solar panels. Here, we design phase-only DOEs by using an iterative optimization algorithm to spectrally split and simultaneously concentrate solar spectrum. In our calculations, we take material dispersion into account as well as the normalized blackbody spectrum of the sunlight. The algorithm consists of the local search optimization and is strengthened with an outperforming lo...
Near-infrared Hong-Ou-Mandel interference on a silicon quantum photonic chip Xu, Xinan; Xie, Zhenda; Zheng, Jiangjun; Liang, Junlin; Zhong, Tian; Yu, Mingbin; Kocaman, Serdar; Lo, Guo-Qiang; Kwong, Dim-Lee; Englund, Dirk R.; Wong, Franco N.C.; Wong, Chee Wei (The Optical Society, 2013-02-25) Near-infrared Hong-Ou-Mandel quantum interference is observed in silicon nanophotonic directional couplers with raw visibilities on-chip at 90.5%. Spectrally-bright 1557-nm two-photon states are generated in a periodically-poled KTiOPO4 waveguide chip, serving as the entangled photon source and pumped with a self-injection locked laser, for the photon statistical measurements. Efficient four-port coupling in the communications C-band and in the high-index-contrast silicon photonics platform is demonstrated,...
Effect of spatial distribution of partial information on the accurate recovery of optical wave fields Öktem, Sevinç Figen (The Optical Society, 2017-01-01) We consider the problem of recovering a signal from partial and redundant information distributed over two fractional Fourier domains. This corresponds to recovering a wave field from two planes perpendicular to the direction of propagation in a quadratic-phase multilens system. The distribution of the known information over the two planes has a significant effect on our ability to accurately recover the field. We observe that distributing the known samples more equally between the two planes, or increasing...
Large format AlInAs-InGaAs quantum-well infrared photodetector focal plane array for midwavelength infrared thermal imaging Ozer, S.; Tümkaya, Umman; Beşikci, Cengiz (Institute of Electrical and Electronics Engineers (IEEE), 2007-09-01) We report the first large format (640 x 512) AlInAs-InGaAs quantum-well infrared photodetector (QWIP) focal plane array (FPA), and investigate the characteristics of AlInAs-InGaAs QWIPs both at pixel and FPA level. The measurements on the detectors fabricated with molecular beam epitaxy grown epilayer structure including 30 InGaAs quantum wells (26 A thick, N-D = 2 x 10(18) cm(-3)) yielded very promising characteristics. The detectors with lambda(p) = 4.2 mu m and Delta lambda/lambda(p) = 25% displayed a ba...
