In this paper we study de response time and sensitivity of a previous reported fiber optic sensor network, multiplexed in the time and spatial domain. As functions of ring resonator coupling coefficient (K) and fiber optic sensor attenuation (A). The network is studied without a frequency based self-reference as previously reported. The response time is defined as the time needed to reach the 95% of the steady state total output power different to the previous work. We find better sensitivities for K and A of 0.99 and 1 respectively. And bigger response times for K and A of 0.02 and 1 respectively.
Scalable integrated optics platforms based on silicon-on-insulator allow to develop optics and electronics functions on
the same chip. Developments in this area are fostered by its potential as an I/O technology that can meet the throughputs
demand of future many-core processors. Most of the optical interconnect designs rely on small footprint and high power
efficiency microring resonators. They are used to filter out individual channels from a shared bus guide. Second-order
microring filters enable denser channel packing by having sharper pass-band to stop-band slopes. Taking advantage of
using a single physical ring with clockwise and counter-clockwise propagation, we implement second order filters with
lower tuning energy consumption as being more resilient to some fabrication errors. Cascade ability, remote stabilization
potential, energy efficiency along with simple design equations on coupling coefficients are described. We design
second-order filters with FWHM from 45 GHz to 20 GHz, crosstalk between channels from -40 dB to -20 dB for
different channel spacing at a specific FSR, with energy efficiencies of single ring configurations and compatible with
silicon-on-insulator (SOI) state of the art platforms.
