Individual Differences in Loss Aversion and the Effects on Well-being A Mixed-Methods Approach

该项目侧重于光通信领域雪崩光电二极管（apd）的开发。这包括对InGaAs的欧姆接触和AlGaAsSb的雪崩倍增的研究。InGaAs PIN二极管的测量结果表明，触点和键垫没有充分优化，可能对带宽产生负面影响。发现具有InGaAs接触层的AlGaAsSb APD的增益带宽积为224 GHz。研究了利用光子带隙实现波分复用的方法。这可能是提高光通信系统数据传输速率的一种潜在方法。设计了具有8 ~ 10个通道的光子晶体解复用器，传输效率为30 ~ 40%，但占用空间较小。

The project focused on the development of avalanche photodiodes (APDs) in optical telecommunications. This involved investigation of ohmic contacts on InGaAs and avalanche multiplication of AlGaAsSb. Measured results from the InGaAs PIN diode suggest that the contacts and bond pads were not sufficiently optimised and can have a negative impact on the bandwidth. The AlGaAsSb APD with InGaAs contact layer was found to have a gain-bandwidth product of 224 GHz. An investigation of wavelength division multiplexing, using photonic bandgap, was investigated. This could be a potential way of increasing the data transmission rates in optical telecommunication systems. A photonic crystal demultiplexer was designed with 8-10 channels, 30-40% transmission efficiency but a relatively small footprint.
