The primary research interest of this investigation include the fundamental limits to the high speed response of optoelectronic devices and inventing ways to surpass those limits. Specifically, the first priority will be to demonstrate the first colliding pulse mode (CPM) locked semiconductor laser. Recently, the PYI and a UCSB graduate student demonstrated a ten times reduction (to 560fs) in the shortest pulses ever obtained from an actively mode locked laser. Based on this research, it is felt that further reduction in pulse width is possible. Other related interests include the study and demonstration of high speed semiconductor lasers, modulators and photodetectors, capable of modulation at 16 Gbits/s and perhaps even higher bit rates. Specifically the investigator is involved in the integration of superlattice waveguide photodetectors with coplanar striplines to demonstrate shorter impulse responses than has ever been previously demonstrated in PIN or Schottky photodetectors, and simultaneously to solve the bandwidth-efficiency product problem that is supposedly inherent to such structures.

本研究的主要研究兴趣包括光电器件高速响应的基本限制和发明超越这些限制的方法。具体来说，第一要务将是演示第一个碰撞脉冲模式（CPM）锁定半导体激光器。最近，PYI和UCSB的一名研究生演示了从主动锁模激光器获得的最短脉冲减少了10倍（降至560fs）。在此基础上，认为进一步减小脉冲宽度是可能的。其他相关兴趣包括高速半导体激光器，调制器和光电探测器的研究和演示，能够以16 gbit /s甚至更高的比特率调制。具体来说，研究者参与了超晶格波导光电探测器与共面带状线的集成，以证明比以前在PIN或肖特基光电探测器中证明的更短的脉冲响应，同时解决了这种结构固有的带宽效率乘积问题。
