color Free Operation of dense wdm pon based on the wavelength locked fabry pe spl acute rot laser diodes injecting a low noise bls
IEEE Photonics Technology Letters, 2006Co-Authors: Ki-man Choi, Jin-serk Baik, Changhee LeeAbstract:We demonstrate color-Free Operation of a dense wavelength-division-multiplexing passive optical network based on the wavelength-locked Fabry-Peacuterot laser diodes with injection of a low-noise broadband light source (BLS). The color-Free Operation, i.e., wavelength-independent Operation, was obtained at 50-GHz channel spacing with the help of a narrow injection bandwidth of the low-noise BLS. We also demonstrate three-channel upstream transmission with 100-Mb/s Manchester coded data

25 gbps error Free Operation of chip scale si photonics optical transmitter over 70 c with integrated quantum dot laser
Optical Fiber Communication Conference, 2016Co-Authors: Kenichiro Yashiki, Kenji Mizutani, Jun Ushida, Yasuyuki Suzuki, Mitsuru Kurihara, Masatoshi Tokushima, Junichi Fujikata, Yasuhiko Hagihara, Kazuhiko KurataAbstract:Si-photonics optical transmitter is fabricated using quantum dot laser (QDL) light sources for multimode-fiber (MMF) transmission. Error Free Operation at 25 Gbps over 70°C is attributed to superior high-temperature characteristics of the QDL and a wider range of acceptable beam directions for coupling to MMF using a grating coupler (GC).

25 gbps ch error Free Operation over 300 m mmf of low power consumption silicon photonics based chip scale optical i o cores
IEICE Transactions on Electronics, 2016Co-Authors: Kenichiro Yashiki, Yasuyuki Suzuki, Mitsuru Kurihara, Masatoshi Tokushima, Yasuhiko Hagihara, Toshinori Uemura, Kazuhiko KurataAbstract:Aiming to solve the input/output (I/O) bottleneck concerning next-generation interconnections, 5 × 5-millimeters-squared siliconphotonics-based chip-scale optical transmitters/receivers (TXs/RXs)— called “optical I/O cores”—were developed. In addition to having a compact footprint, by employing low-power-consumption integrated circuits (ICs), as well as providing multimode-fiber (MMF) transmission in the O band and a user-friendly interface, the developed optical I/O cores allow common ease of use with applications such as multi-chip modules (MCMs) and active optical cables (AOCs). The power consumption of their hybrid-integrated ICs is 5mW/Gbps. Their high-density user-friendly optical interface has a spot-size-converter (SSC) function and permits the physical contact against the outer waveguides. As a result, they provide large enough misalignment tolerance to allow use of passive alignment and visual alignment. In a performance test, they demonstrated 25-Gbps/ch error-Free Operation over 300-m MMF. key words: Si photonics, low-power-consumption, small footprint, high density interface, I/O bottleneck

35 Gbit/s error-Free Operation of 980nm DBR laser with integrated electroabsorption modulator
Electronics Letters, 2007Co-Authors: C. S. Wang, Yuchia Chang, Larry A. ColdrenAbstract:High-speed, single-frequency transmitters at 980 nm are reported, with open eye diagrams up to 40 Gbit/s and error-Free Operation up to 35 Gbit/s. The transmitters consist of a short-cavity, distributed Bragg reflector (DBR) laser with an integrated electro absorption modulator fabricated using a quantum well intermixing processing platform. This represents the fastest bit-rate Operation to date from a single transmitter in the 830-1100 nm datacom wavelength range.

Study of chirp-Free Operation for guide/antiguide modulator
IEEE Photonics Technology Letters, 1992Co-Authors: T. C. Huang, Larry A. Coldren, T. C. Yang, Z.m. Chuang, Youngchul Chung, Nadir DagliAbstract:A method of achieving chirp-Free Operation of a field-induced guide/antiguide intensity modulator is reported. Both measured and calculated data for chirp-Free Operation are demonstrated for a 1.15- mu m wavelength. In a push-pull mode of Operation, the index in the guide and antiguide regions of the modulator change in opposing directions, which can be adjusted such that the resulting phase shift contributions to the guided mode cancel each other, resulting in zero net mode phase shift. >
