We report the design, construction, and test of a compact fiber-optic gyroscope (FOG) for cost-effective low-earth-orbit CubeSat applications. This medium-grade FOG is developed by the integration of a miniaturized (16-mm long) multifunction integrated optic circuit and a streamlined feedback electric-optical control logic module. The whole structure layout of the FOG has been carefully designed and optimized to effectively reduce the weight of the unit in a 1U (10x10x10 cm3) space.

We propose a two-stage pipelined parallel matching scheduler for alleviated scheduling time constraint. TPPM with pGA provides ~100% throughput and maximum ~42% less queuing delay when offered load is above 0.6 than single DRRM scheduler.

We propose and demonstrate a high-resolution frequency-domain equalization scheme for dual-polarization optical IQ modulator, where time-interleaved optical multitone signals are generated and successfully demodulated. We verify the effectiveness of the scheme in 4/16/64-QAM signal generation.

EMLs for ultra-high data-rate modulation is subject to the residual facet reflection (RFR). We verify by simulation and experiments the enhanced immunity to RFR for uncooled EMLs by incorporating partial-corrugated-grating (PCG) in the laser section.

A smart cushion based on SFS (single-mode-few-mode-single-mode) structure is proposed and experimentally demonstrated, which can be applied in physiological and activity states monitoring simultaneously. The sensing unit embedded in a common cushion is designed as a sandwich structure, consisting of a piece of fiberglass mesh, a SFS structure layer and a polyvinyl chloride (PVC) layer thus the sensitivity can be significantly enhanced. With off-line processing and analyzing of the raw signals collected from the cushion system, the heartbeat rate (HR) and respiratory rate (RR) can be obtained with the maximum error of 1 bpm and the activity states on the cushion can be clearly distinguished within the accuracy of one second. Such a smart cushion has the advantages of low cost, compact structure and high comfort, especially suitable for office workers and the elderly in nursing homes.
