“…When the leftmost add/drop filter is tuned to resonate, the delay time of about 300 ps is observed. The pulse delay characteristics through add/drop filters and the delay lines are also simulated using a split‐step time‐domain modeling approach . The simulation results assuming the target design coupling ratios of 0.4 and 0.08 for bus–ring and ring–ring couplers are shown in Figure .…”

Variable optical signal delay devices composed of cascaded double ring add/drop filters and delay waveguides are designed and fabricated. In the measurement, variable time delay is observed in proportion to the number of delay lines. The experimental results exhibit the potential for the fabricated delay device to be applied to an optical code division multiple access encoder/decoder. © 2015 Wiley Periodicals, Inc.

“…Many research efforts have focused on the development of optical resonators based on microfibers, which are very useful for many applications to optical filters and sensors [5][6][7][8][9][10]. The optical resonators based on microfiber are very sensitive to a change in the surrounding environment due to the large evanescent field in the microfiber [11,12].…”

A highly sensitive current sensor based on an optical microfiber loop resonator (MLR) incorporating low index polymer is proposed and experimentally demonstrated. The microfiber with a waist diameter of 2 m is wrapped around the nichrome wire with low index polymer overlay to realize the MLR as the highly sensitive current sensor. Low index polymer overlay can successfully reduce round-trip fractional loss resulting in the improvement of the Q-factor (Q) and the finesse (F) of the MLR around the nichrome wire. The use of the microfiber with a waist diameter of 2 m and low index polymer with high thermal property can effectively improve the current sensitivity of the proposed MLR to be 437.9 pm/A 2 .

Single-ring all-pass filters with various coupling ratios are designed, fabricated, and characterized to assess the validity of the split-step time-domain modeling approach, which is considered for direct simulation of time-domain characteristics, such as optical delay, of various ring resonator devices. When the coupling ratio of the single-ring all-pass filter is 0.4 and 0.8, the delay time is measured to be about 145 and 42 ps respectively, which is comparable to the time-domain modeling results of 151 and 47 ps respectively. The measurements for two-and three-ring all-pass filters are also found to agree quite well with the simulation results. With these results it is confirmed that the split-step time-domain model could be efficiently incorporated into an optical-communication simulation module for ring resonator delay components in an all-optical packet switching system.
