项目摘要
1.Fabrication of Chirped gratings by weighted electron beam exposure and their application to DFB lasers : By combining a field size modulation technique with the weighted electron beam exposure, we successfully fabricated linearly chirped gratings (CGs). Then, we applied them to distributed feedback (DFB) laser fabrication, and observed optical bistability in the CD DFB lasers. The optical power necessary to excite the bistability was found to be one fourth of conventional DFB lasers, and the wavelength range within which the bistability was observed was twice as large as the conventional ones.2.Mass-transported InAsP compressively-strained quantum wire gain-coupled DFB laser fabrication : Mass-transport phenomenon on InGaAsP/InP epitaxial wafers with quarter micron pitch V-grooves was made use of for the fabrication of quantum wire gain-coupled DFB lasers. Amplified spontaneous emission (ASE) around 1.55 μm was observed.3.Wavelength trimming in multiple wavelength gain-coupled DFB la … More yer arrays : Multiple wavelength gain-coupled DFB laser arrays were studied and fabricated as a light source for wavelength division multiplexed (WDM) optical communication. The multiple pitch gratings were formed by electron beam exposure with field size modulation, and the gain coupling was brought about by absorptive gratings. The four wavelength laser array at 1.55μm band fabricated exhibited uniform threshold current distribution and oscillation wavelength spacing. Disordering experiment of a super lattice layer by a pulsed YAG laser beam was conducted for wavelength trimming.4.Temperature insensitive semiconductor laser by strain compensation : Toward "fiber to the home" and its wavelength multiplexing, we studied reduction of temperature sensitivity in laser diode characteristics. More specifically, we tried to cancel out intrinsic temperature dependence by applying mechanical strain to laser diodes with temperature change through novel heat-sink structure. After remodeling of the heat sink, we packaged laser chips on it and demonstrated feasibility of temperature compensation of oscillation wavelength and threshold current by this method.5.All optical_flip-flop based on bistable semiconductor lasers : We proposed a novel bistable directionally coupled semiconductor laser as an all-optical flip-flop important for future all-optical processing. After confirming its effectiveness through theoretical analysis, an actual device was fabricated by utilizing newly developed electrode separation technique. As a result, all-optical flip-flop operation was demonstrated. Less
1.加权电子束辐照啁啾光栅的制备及其在DFB激光器中的应用:将场尺寸调制技术与加权电子束辐照相结合,成功制备了线性啁啾光栅(CGs)。然后,我们将它们应用到分布式反馈(DFB)激光器的制造中,并观察了CD DFB激光器的光学双稳性。激发双稳性所需的光功率是传统DFB激光器的四分之一,观察到双稳性的波长范围是传统激光器的两倍。质输运InAsP压缩应变量子线增益耦合DFB激光器的制备:利用四分之一微米间距v型沟槽InGaAsP/InP外延片上的质输运现象制备了量子线增益耦合DFB激光器。在1.55 μm附近观察到放大自发辐射(ASE)。多波长增益耦合DFB激光器阵列中的波长微调:研究并制作了多波长增益耦合DFB激光器阵列作为波分复用(WDM)光通信的光源。通过电子束辐照和场尺寸调制形成多螺距光栅,吸收光栅带来增益耦合。在1.55μm波段制备的四波长激光阵列具有均匀的阈值电流分布和振荡波长间隔。利用脉冲YAG激光束对超晶格层进行了波长微调的无序实验。基于应变补偿的温度不敏感半导体激光器:针对光纤到户及其波长复用技术,研究了降低激光二极管特性的温度敏感性。更具体地说,我们试图通过新型散热器结构对温度变化的激光二极管施加机械应变来消除固有的温度依赖性。在对散热片进行改造后,在其上封装了激光芯片,验证了该方法对振荡波长和阈值电流进行温度补偿的可行性。基于双稳半导体激光器的全光触发器:我们提出了一种新型的双稳方向耦合半导体激光器作为全光触发器,对未来的全光处理具有重要意义。在通过理论分析证实其有效性后,利用新开发的电极分离技术制作了实际装置。结果证明了全光触发器的操作。少
