Multi-channel control for microring weight banks.
We demonstrate 4-channel, 2GHz weighted addition in a silicon microring filter bank. Accurate analog weight control becomes more difficult with increasing number of channels, N, as feedback approaches become impractical and brute force feedforward approaches take O(2N) calibration measurements in the presence of inter-channel dependence. We introduce model-based calibration techniques for therm...
متن کاملFabrication strategies for filter banks based on microring resonators
Wavelength-division demultiplexers are a fundamental component needed for many proposed integrated photonic systems. By using filter banks based on microring resonators it is possible to create demultiplexers that are two orders of magnitude smaller and achieve better performance than the discrete component demultiplexers currently used. To create a filter bank out of microring resonators the r...
متن کاملThermal stabilization of a microring modulator using feedback control.
We describe and demonstrate the use of a feedback control system to thermally stabilize a silicon microring modulator subjected to a thermally volatile environment. Furthermore, we establish power monitoring as an effective and appropriate mechanism to infer the temperature drift of a microring modulator. Our demonstration shows that a high-performance silicon microring-based device, normally i...
متن کاملquality control in cell banks
cell banking is long –term storing of cell stocks that requires intensive care and maintenance to ensure its adequate quality. the main goal of a biological bank is preparing a repository source of cell culture system in a global manner. on the other hand, cell culture is an invaluable tool for investigators in numerous fields. successful maintenance of cells requires knowledge and practice of ...
متن کاملAssessment of the conventional control algorithms and proposing a modified displacement feedback control for performance-based design of structures
An enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. At first, a comparative study is implemented assessing three most common active control algorithms including state, acceleration, and displacement feedback controls. The advantage of the displacement feedback algorithm for active control of structures against earthquakes is de...
