Abstract
Ordinary Bragg reflectors, also known as one-dimensional photonic band gap
structures (PBGs), display extraordinary linear and nonlinear optical properties
that present a remarkable opportunity: the simultaneous availability of exact
phase matching conditions and field confinement that act together to yield
significantly enhanced second and third harmonic generation, frequency downconversion,
and multi-wave mixing processes. This opens the door to a new
class of micrometer-sized devices that represent a new generation of efficient
parametric sources for up- and down-conversion processes.
