Photonic signal frequency up and down-conversion using a photonic band gap structure
First Claim
1. A device for frequency down-converting a photonic signal incident upon the device, comprising:
- a plurality of first material layers; and
a plurality of second material layers, the first and second material layers being adapted to receive first and second photonic signals incident upon the device and having respective first and second frequencies, the first and second material layers being arranged such that the device exhibits a photonic band gap structure, wherein the photonic band gap structure exhibits first and second transmission band edges respectively corresponding to the first and second frequencies, and wherein an interaction of the first and second photonic signals with the arrangement of layers causes a mixing process to generate a third photonic signal having a third frequency that is less than the first and second frequencies.

Abstract
A photonic band gap (PBG) device is provided for frequency up and/or down-converting first and second photonic signals incident on the device to produce a down-converted output photonic signal. When the first and second incident photonic signals have respective first and second frequencies ω3 and ω2, the down-converted photonic signal has a third frequency ω1=ω3−ω2. When the first incident field has a frequency ω1, the first up-converted photonic signal has a second frequency ω2. The second up-converted photonic signal has a third frequency ω3=ω1+ω2. Thus, the PBG device can be used to generate coherent near- and mid-IR signals by frequency down-converting photonic signals from readily available photonic signal sources, or red, blue, and ultraviolet signals by up-converting the same readily available photonic signal sources.

11. A method of frequency down-converting a photonic signal incident on a device, the device including a plurality of first material layers and a plurality of second material layers, the first and second material layers being arranged such that the device exhibits a photonic band gap structure, wherein the photonic band gap structure exhibits first and second transmission band edges, the method comprising the steps of:
applying first and second photonic signals to the first and second material layers, the first and second photonic signals having respective first and second frequencies corresponding to the first and second transmission band edges, wherein an interaction of the first and second photonic signals with the arrangement of layers causes a mixing process to generate a third photonic signal having a third frequency that is less than the first and second frequencies. - View Dependent Claims (12, 13, 14)
