OPA: Optical Parametric Amplifiers

Summary: 

Fiber optical parametric amplifiers (OPAs) are based on the third-order susceptibility of the glasses making up the fiber core. OPAs boast advantages, like increasing bandwidth with increasing pump power, arbitrary center wavelength, large gain, idler generation, and high-speed optical signal processing, which make it a promising technology for application and band conversion in future wavelength-division multiplexing(WDM) systems and next-generation optical networks. 

Accomplishments

  1. OPA with 400nm gain bandwidth has been experimentally demonstrated
  2. Good results have been obtained for polarization-insensitive OPAs
  3. Schemes has been proposed to reduce nonlinear crosstalk significantly in both one-pump and two pump OPAs
