Compact and wideband optical 90o hybrid based on a one- way tapered MMI coupler
Compact wideband optical 90o hybrid based apered MMI coupler
2015/5/21
We report compact and wideband 90o hybrid with a one-way tapered 4×4 MMI waveguide. The fabricated device with a device length of 198 μm exhibited a phase deviation of <±5.4o over a 70-nm-wide spectra...
Optical Memory Elements with Extremely Wide Hysteresis Window (94mA) Using Partly Saturable-Absorber Novel Active MMI Bi-Stable Laser Diodes
Opto-electronics Optical switching devices
2015/6/4
Novel active MMI bi-stable laser diodes are proposed and demonstrated. Using partly saturable-absorber configuration in active MMI, extremely wide hysteresis window of 94mA was achieved with 30fJ opti...
MMI-Reflector: A Novel On-chip Reflector for Photonic Integrated Circuits
MMI-Reflector Novel On-chip Reflector Photonic Integrated Circuits
2015/7/17
We present a novel, compact, on-chip multi-mode interference (MMI) reflector, with near-100% theoretical reflection. We measured 78±10% reflection for an InP-based MMI-reflector fabricated with a sing...
Integrated 4-bit Optical Memory Elements with Single Common and Low Operation Current (55mA) Using Novel Active MMI
Integrated Optical Memory Elements Operation Current (55mA) Novel Active MMI
2015/7/17
Integrated 4-bit (355x1200 μ m 2 ) optical memory elements, using novel active multi-mode-interferometer bi-stable laser diodes, showed single, common and low operation current (55mA) with uniform cha...
A Novel Active MMI Bi-Stable Laser Using Cross-Gain Saturation between Fundamental and First Order Modes
Active MMI Bi-Stable Laser Cross-Gain
2015/8/4
A novel MMI-based bi-stable laser is proposed for realizing compact size. Relatively low operation current of 100mA (8mA hysteresis), and high ON/OFF optical power-ratio of 15dB were successfully achi...
人类基因组序列的破译提供人类基因最基本的结构信息，同时一些功能性基因组技术的出现，如基因芯片技术、微阵列比较基因组杂交技术、蛋白质组学技术的产生，人们越来越渴望从组织切片上，获取某一特定的同类细胞，从而对这些或者个细胞内癌基因、抑癌基因﹑侵袭转移相关蛋白、信号转导蛋白、细胞增殖和分化相关蛋白等进行研究，但以往各种技术所获得的细胞都不可能是单一同类细胞群。显微切割（microdissection）技...
Analyzing the MMI MZI optical switches by field transfer matrix method
MMI MZI optical switches transfer matrix method
2010/7/15
Multimode interference (MMI) Mach-Zehnder optical switches consist of MMI splitters and recombiners interconnected by single mode guides, which act as phase shifters. Based on the phase relations of t...
