“…We can also control the delay by changing the refractive index of the resonators or the coupling region through the electro-optic or thermo-optic effect. [27][28][29][30] However, as ͉͉ decreases, so does the bandwidth of the CROW, and the overall loss of the CROW becomes more sensitive to the intrinsic losses in the individual resonator. The latter effect occurs because the light spends more time in a resonator before tunneling to its neighbor.…”

We address the trade-offs among delay, loss, and bandwidth in the design of coupled-resonator optical waveguide (CROW) delay lines. We begin by showing the convergence of the transfer matrix, tight-binding, and time domain formalisms in the theoretical analysis of CROWs. From the analytical formalisms we obtain simple, analytical expressions for the achievable delay, loss, bandwidth, and a figure of merit to be used to compare delay line performance. We compare CROW delay lines composed of ring resonators, toroid resonators, Fabry-Perot resonators, and photonic crystal defect cavities based on recent experimental results reported in the literature.

“…Directly tunable filters have also been developed [8], giving tuning ranges up to 62 nm and linewidths as small as 0.6 nm and aborption efficiency of 20%, with linewidths less than 1 nm over a 40 nm range. Smaller linewidths have also been reported [6] -0.27 nm and a tuning range of 32 nm with 5.5 period TiO 2 /SiO 2 Bragg mirrors; however analysis of sensitivity to tilt angle showed that 0.02 tilt resulted in an absorption drop of 18.2 dB.…”

We describe the first iteration of a comprehensive model with which we can investigate the practical limits on optical bus bandwidth and number of bus processing modules for given signal power. The selection algorithm will ultimately allow programmable evaluation of system parameters bus bandwidth, optical power budget, electrical power budget, number of modules and space consumption for an optimal design that is suited to on-the-fly system reconfiguration.

“…MEMS-based Fabry-Perot filters have been successfully applied to the telecommunications arena for wavelengthdivision multiplexing (WDM) applications, as the wavelengthselecting component in both wavelength-tunable sources and wavelength-tunable sensors [1]. Such applications require high spectral resolution (~1 nm) and relatively small tuning ranges (typically ~100 nm in the 1550 nm telecommunications wavelength band).…”

A wavelength-tunable bandpass optical filter based on a Fabry-Perot cavity combined with a micro-actuator has been designed and fabricated, with an emphasis on achieving a wide tuning range. The measured tuning range of 1620 nm to 2425 nm is the largest reported for a MEMS-based Fabry-Perot filter, and is achieved by utilizing the strain stiffening effect in fixed-fixed beam actuators. This paper describes the optical design of the Fabry-Perot cavity, the mechanical design of the actuators, the fabrication process, and the measurement of both the device transmittance and the physical movement of the actuators. There is excellent agreement between the theoretical and measured transmittance of the filters when the small curvature in the top mirror of the Fabry-Perot cavity is accounted for.
