Abstract:
A microresonator for delaying photonic signals of a predetermined frequency, the microresonator comprising:a pair of switchable mirrors that are spaced apart to define a microresonator cavity therebetween, wherein each mirror is controllably switchable between a transmissive state in which photonic signals enter and exit the microresonator cavity and a reflective state in which photonic signals are internally reflected within the microresonator cavity; anda photonic bandgap delay apparatus having a photonic band edge resonance at the predetermined frequency of the photonic signals, wherein said photonic bandgap delay apparatus is disposed within the microresonator cavity defined by said pair of mirrors for delaying the photonic signals during each pass of the photonic signals through the microresonator cavity to thereby impart an adjustable delay to the photonic signals.
