The first sub-100nm technology that allows the monolithic integration of optical modulators and germanium photodetectors as features into a current 90nm base highperformance logic technology node is demonstrated. The resulting 90nm CMOS-integrated Nano-Photonics technology node is optimized for analog functionality to yield power-efficient single-die multichannel wavelength-mulitplexed 25Gbps transceivers.
We propose a new design of 25-GHz flat-top multichannel optical filter. The flat-top of optical filters can improve to 2.288×10-11dB which is superior to that of 5 orders of previous study. The superior performance of dispersion and channel spacing isolation improve 73.5% and 94%, respectively, which compared with previous study.

We experimentally demonstrated an adaptive I/Q imbalance correction scheme to compensate I/Q-imbalance. With I/Q correction, a 32.65-Gbps OFDM signal at 60 GHz within 7-GHz license-free band is successfully generated and, following 25km SMF transmission, negligible power penalty is observed.
Detection of chlorophyll a is important in the protection of marine ecosystem. This paper focused on designing and developing a high-sensitivity, low-power instrument (Named HME Chlometer) for chlorophyll a measurements. Chlorophyll a samples of different concentration were measured, using HME Chlometer and Seapoint Chlorophyll Fluorometer for comparison, and the result showed HME Chlometer was of...
A flat-top 25 GHz optical interleavers based on a ring cavity with spectral characteristics demonstrate in the following. Also, group velocity dispersion and ripple as well as phase of reflector have improved a lot with dispersion compensators.
A flat-top of 50-GHz Mux/Demux of DWDM exhibits a characteristic of 2.25×10−5 dB, an improvement of 2-order than previous study. The channel isolation reaches a high performance of 52.89dB, which is better than the previous study 16.51dB. The dispersion has a more than 50% enhancement compared to the previous investigations.
