Patent ID: 7346248

Claim:
A photonic bandgap light manipulation apparatus having a tunable property, comprising: a photonic bandgap structure having a dispersion relation, said photonic bandgap structure comprising a ferroelectric material, said photonic bandgap structure having at least one of an optical input port for receiving an optical input signal and an optical output port for providing an optical output signal; a control circuit that controls an application of a tuning signal to said ferroelectric material; and at least one structure operatively connected to said ferroelectric material and to said control circuit, said at least one structure configured to apply said tuning signal to said ferroelectric material; whereby said property of said photonic bandgap light manipulation apparatus is tuned to provide a manipulation of at least one of said optical input signal that is received at said apparatus at said optical input port and said optical output signal that is provided by said apparatus at said optical output port.
