Two-dimensional photonic crystal slab apparatus and a method for fabricating two-dimensional photonic crystal slab apparatus. A two-dimensional photonic crystal slab apparatus has a photonic crystal slab containing a two-dimensional periodic lattice, and upper and lower cladding layers for the photonic crystal slab, the upper and lower cladding layers each having a metallic cladding layer. The metallic cladding layers permit achieving substantially perfect light transmission through a waveguide in the slab, even when the waveguide is strongly bent. The fabrication method includes forming a two-dimensional photonic crystal slab from a dielectric slab supported on a substrate by, for example, an etch process.

A photonic crystal waveguide apparatus has a photonic crystal having a waveguide which is capable of transmitting light having a frequency within a bandgap of the photonic crystal, and a resonant stub connected to the waveguide to control light in the waveguide. The resonant stub has a resonator region and a connecting channel which connects the resonator region to the waveguide. The resonant stub controls light transmission characteristics of the waveguide by creating a transmission zero in the transmission band of the waveguide. A tuner for tuning the resonant stub may also be provided to control the transmission zero to provide an active optical apparatus such as an on/off switch or a modulator.

A tunable optical cavity constructed from a fixed mirror and a movable mirror. The fixed mirror is attached to a substrate having a first electrically conducting surface. A support member having the moveable mirror supported thereon and having a second electrically conducting surface, is suspended above the substrate. A circuit applies an electrical potential between the first and second electrically conducting surfaces thereby adjusting the distance between the fixed and movable mirrors. The fixed mirror and the moveable mirror are positioned such that the mirrors form the opposite ends of the optical cavity. The distance between the fixed mirror and the moveable mirror is a function of the applied electrical potential. The support member has physical dimensions that are chosen such that the amplitude of thermally induced vibrations in the support member are less than 0. 01 percent of the wavelength of the resonating light.

A photonic crystal drop filter apparatus and a method for tuning a photonic crystal drop filter. The photonic crystal drop filter has a photonic crystal having first waveguide for transmitting light having a frequency within a bandgap of the photonic crystal, and a second waveguide. The second waveguide is connected to the first waveguide by a resonant cavity for extracting at least one wavelength of the light transmitted by the first waveguide and redirecting the extracted light to the second waveguide. A tuning device is included in the apparatus to tune the wavelength of the extracted light over a full range of wavelengths. The apparatus is particularly suitable as an extraction device for optical communications systems such as a WDM communications system wherein it is necessary to extract one or more carrier signals from a plurality of carrier signals.

A photonic crystal interferometric switch has a photonic crystal; a waveguide in the photonic crystal, the waveguide having at least one input portion, at least two output portions and an interference channel connecting the at least two output portions, the waveguide capable of transmitting light within a bandgap of said photonic crystal; and a resonant member connected to at least one of the at least two output portions to control a property of light in the at least one output portion, to control the interference of light in the waveguide. A 1Ã2 optical switch may be constructed by tuning the parameters of the resonant member, either optically or electronically, resulting in a switching of a light signal from one output portion to another output portion. Furthermore, by isolating one output portion of the interferometer, the apparatus may be utilized as an optical modulator.

The CRCSEL comprises a single-mode optical gain structure and an optically-resonant cavity. The single-mode optical gain structure is structured to generate excitation light having a wavelength and a direction. The optically-resonant cavity is optically coupled to the single-mode optical gain structure and is structured to emit an output light beam in a direction substantially orthogonal to the excitation light. The change in light direction provided by the optically-resonant cavity enables the output light beam to emit from a surface while allowing the excitation light to be generated in a large, high-gain single-mode optical gain structure.

Optically resonant systems for redirecting optical signals are provided. A representative optically resonant system includes a first structure in a plane. The first structure reflects optical radiation in a first direction substantially orthogonal to the plane. The optically resonant system further includes a second structure overlapping the first structure. The second structure optically communicates with the first structure, and reflects optical radiation substantially parallel to the plane. The first and second structures operate to capture at least a portion of a first optical signal propagating substantially parallel to said plane by exciting a resonant signal in the resonant cavity through the resonant characteristics of the first and second structures. The first and second structures further operate to emit said resonant signal in a second direction substantially orthogonal to said plane. Methods and other optically resonant systems also are provided.

An optical structure is formed on a surface of the optically resonant system to modify a characteristic of the emitted resonant signal. The optical structure may be configured to impart a phase-shift on a portion of the resonant signal. Because the resonant signal consists of a single resonant mode with an axially symmetric radiation pattern, a phase-shift can be used to, for example, collimate, disperse, direct, and generally shape output characteristics of the emitted resonant signal. The optical structure can also be used to tune the quality factor (Q) of the optically resonant system.
