Multiple strip lines for picosecond optoelectronic pulses
Abstract
Picosecond electrical pulses on coplanar transmission lines generated by femtosecond laser pulses have very sharp rising edges but longer tails dependent on the carrier lifetimes. It is difficult to limit the carrier lifetimes below one picosecond. To obtain enhanced far-infrared power in the frequency band above 1 THz a 'frozen wave' design with fast alternation of rising edges from positive and negative lines is proposed. Details of the design are discussed.
