    摘要： A reconfigurable optical device including input and output ports, and add or drop ports, has a high degree of flexibility such that any wavelength channel from any optical signal introduced through the add ports may be added to any of the optical signals transmitted through the output ports. In addition, any wavelength channel from any optical signal received through the inputs ports may be dropped through any of the drop ports. Furthermore, the optical device is configurable to allow the same wavelength channel from two different optical signals supplied respectively through any two inputs ports to be simultaneously directed to two different drop ports.

    摘要： A light detector measures optical power of light incident thereon. Using a beam steering device that is rotatable about two orthogonal axes, wavelength components of different channels are scanned onto the light detector in accordance with programmable parameters. The programmable parameters specify the light detector to which the wavelength components are directed, the order the wavelength components are monitored by the light detector, and the time duration over which each of the wavelength components is monitored by the light detector.

    摘要： A temperature compensated optical filter assembly including a plurality of thin films having temperature dependent indices of refraction which are deposited on a glass substrate so as to form a conventional interference filter thereon. The glass substrate is adhesively coupled to a metal holder such that the deposited thin film interference filter is interposed between the glass substrate and an adhesive layer distributed along a mounting surface of the holder. Thus, a first thermal mismatch stress is applied by the glass substrate onto an inner layer of the interference filter and a second mismatch stress is applied by the holder onto an outer layer of the interference filter, wherein the first and second mismatch stresses depend on the temperature of the filter assembly. The glass substrate, the adhesive, and the holder are preferably formed of materials having mechanical properties such that the first and second mismatch stresses compensate for the effects of the temperature dependent indices of refraction of the thin films so as to uniformly maintain the spectral performance of the filter assembly in response to a change in temperature. In one embodiment, an additional degree of freedom is obtained by electro/magneto-strictively prestressing the thin film stack during the formation thereof. In another embodiment, an active stress management system is utilized.

    摘要： Wavelength dispersion and spatial light modulation are combined having regard for polarization management within a feedback control system for dynamically adjusting spectral power distributions among different wavelength channels. Micro-optic, hybrid, and planar implementations are proposed along with coupling schemes to larger fiber optic systems. Utility is found throughout multi-channel wavelength division multiplexing (WDM) transmission systems.

    摘要： A photodiode (PD) array accurately measures incident optical power on each of the PDs in the array by eliminating the effect of crosstalk between the individual PDs. Crosstalk within the PD array is removed by measuring the current generated by each PD in the array and generating a corrected optical power value for each PD that is based on the measured current for each PD and on coupling coefficients associated with other PDs in the array. The coupling coefficients are determined during a previous calibration procedure.

    摘要： The present invention generally relates to the operation of optical network equipment such as optical amplifiers. In one aspect, a method of operating an optical amplifier is provided such that output of the optical amplifier avoids the effects of operating an optical gain medium in a non-linear (kink) region of an L-I curve. The method generally includes operating an optical gain medium in a fully off state or fully on state above the kink region with a PWM signal. In another aspect, the effects of the kink region may be compensated for by utilizing a lookup table. A sample of the optical power of an amplified optical signal may be used to select an entry in the lookup table that compensates for non-linearities in the kink region. In yet a further aspect, a lookup table may be used to control a pulse modulator to compensate for non-linearites in the kink region of the L-I curve.
