Abstract :
An ultrashort electrical pulse with a pulse width of 3.3 ps was generated successfully from an ordinary metal-semiconductor-metal photodetector simply by adding an input resistor and hold capacitor. The new detector not only provides ultrashort fall time, but also has other advantages such as ease of fabrication, high sensitivity, and low-bias operation.
