Time Domain Corporation proposes novel devices for achieving second harmonic generation in Laser Systems. The result will be a micro-size, layered, periodic, Semiconductor structure or a fiber Bragg grating that will perform several orders of magnitude better than devices in use today. Most second harmonic crystals that are currently used are of millimeter=size or greater. The simple design of current crystals makes it very hard to decrease their size in a cost effective manner without losing efficiency. They are made of materials that are expensive and cannot be combined easily with other materials. They are also non-linear which requires them to be used with very powerful laser sources only. The device proposed is just several microns thick and is made of common semiconductor materials. This allows it to be used easily with other semiconductors or made into a standard integrated circuit chip. The device also works on a linear principle which allows it to be used with very low power laser sources at amuch higher efficiency. this photonic bandgap based structure is revolutionary not only because it is orders of magnitude more efficient, but orders of magnitude smaller while made of very inexpensive material. Using the same physical principles. We also propose calibration of a fiber Bragg grating for non-linear conversions for fiber optic applications.
