Frequency doubling (or second-harmonic generation) is the phenomenon that an input wave in a nonlinear material can generate a wave with twice the optical frequency.

Nevertheless, second-harmonic generation (SHG) with peak power-conversion efficiency as high as ~3% has been reported to occur in optical fibers in 1986 [1]. Initially, this phenomenon could not be reasonably explained by core-cladding interface or bulk multipole moment contributions to the secondorder nonlinearity [2].

Meta-Materials & Meta-Devices - ULTRAFAST & NANOSCALE With state-of-the-art optical setups available for in-waveguide and free-space second-harmonic generation, measurements were/can be performed on both silicon nitride thin-films (using pico-second pulsed laser sources) and waveguides (using CW sources), showing values as high as 2pm/V for the nonlinear coefficient. 1 -7, Y - - Spatial Frequency Multiplier with Active A frequency multiplier with active linearly tapered slot antennas (LTSAs) has been demonstrated at the second harmonic frequency. In each antenna element, a GaAs monolithic microwave integrated circuit (MMIC) distributed amplifier is integrated with two LTSAs. The multiplier has a very wide bandwidth and large dynamic range.
