    Abstract: An optical add/drop multiplexing (OADM) device includes two MMI structures connected by a MI/MZI waveguide structure comprising a wavelength selector that includes phase shifted Bragg gratings. The OADM multiplexer transmits a wavelength channel selected in advance and reflects all other channels to achieve a drop functionality. Simultaneously, a further channel may be added to the multiplexer at the same side as the channel selected in advance is output. The further channel preferably is centered around the same wavelength as the channel selected in advance. The further channel is transmitted through the Bragg gratings and is superimposed with the other channels to achieve an add functionality.

    Abstract: A coupler-multiplexer permutation switch (CMPS) integrates multiplexng and switching functions on a single substrate. It has a single-mode/multi-mode backward coupler followed by a digital optical switch (DOS). In the CMPS, the single-mode waveguide channels are phase-matched through a grating with the corresponding, backward-propagating modes of a multi-mode waveguide. The different modes are subsequently separated in a digital optical switch. Different permutations are obtained by electronically controlling an effective-index distribution of DOS output waveguides.

    Abstract: A reciprocating optical modulator includes a continuous light path fulfilling an amplification function, an optical modulation part formed on the light path, a first optical band-pass filter and a second optical band-pass filter formed to nip the optical modulation part therebetween and a device to introduce exciting light for exciting the light path. The optical modulation part, first and second optical band-pass filters and device are disposed on the light path as formed in a single optical crystal or in a multiplicity of optical crystals. The first optical band-pass filter admits incident light and reflects light having the incident light modulated. The second optical bandpass filter reflects the incident light and emits the light having the incident light modulated. The modulator can also include a third optical band-pass filter disposed between the optical modulation part and the second optical band-pass filter for removing the incident light.

    Abstract: A grating coupled surface plasmon resonance optical modulator is disclosed. A electro-optic polymer dielectric is deposited on the metallic surface of a diffraction grating to provide a metal/dielectric interface. A surface plasmon will propagate at the metal/dielectric interface in a resonant condition, e.g., when the metal surface is illuminated by transverse magnetic (TM) polarized light of the appropriate wavelength, angle of incidence and phase velocity. In the present invention, phase velocity is controlled by the diffraction grating. A transparent electrode deposited on the electro-optic layer allows an electrical potential to be applied across the electro-optic polymer. The applied electrical potential (voltage) changes the index of refraction of the electro-optic polymer, thereby disrupting the resonant condition to produce an optically detectable change in reflectance of incident light from the metal layer. The disclosed grating coupled surface plasmon resonance optical modulator may be configured as an electronically or optically addressable array.
