Mirror-assisted Surface Grating Couplers Realized with Standard Bulk CMOS Processes
Li-Chi Yang,Yung-Jr Hung,San-Liang Lee,Poki Chen,Ying-Ting Liu,
We have successfully designed and demonstrated a mirror-assisted grating coupler on a standard CMOS configuration. Existing metal layer is utilized to improve the directivity of the grating coupler, thus enhance the coupling efficiency by 5.5 dB according to the simulation results. As-realized grating coupler is characterized to operate at 1570 nm having a 1-dB bandwidth of 28 nm. A 7.5 dB improvement in coupling efficiency happens in metal-assisted grating couplers, indicating the effectiveness of this design concept.

All optical modulation format conversion from 4x12.5 Gbps NRZ-OOK to 50 Gbps PDM RZ-QPSK based on cross-phase-modulation in a bidirectional scheme
Yu-Hsiang Wen,Jia-Wei Ho,Yi-Ting Liao,Tzu-Yu Yeh,Kai-Ming Feng,
We proposed a bidirectional all-optical modulation format converter by applying XPM in a single HNLF. 4 individual 12.5 Gbps NRZ-OOK signals are converted to a 50 Gbps PDM RZ-QPSK signal with a satisfactory power penalty. The performance and feasibility of the proposed converter are investigated both theoretically and experimentally.

Suppressing the Colorless Laser Diode Induced Intensity Noise for 256-QAM-OFDM transmission at 40 Gbit/s
Cheng-Ting Tsai,Yu-Chieh Chi,Gong-Ru Lin,
The directly modulated colorless laser diode carried 256-QAM-OFDM transmission at 40 Gbit/s is demonstrated by suppressing the spontaneous emission and the relaxation oscillation related intensity noise. After transmitting through the 25-km single-mode fiber, the BER and the EVM of the transmitted 256-QAM-OFDM data can be optimized to 5.7E-3 and 4.8%, respectively.

Highly Sensitive Refractive Index Sensor Based on Fiber-optic Fabry-Pérot Interferometer Formed by Inclined Fiber
Hsuan Chen,Chun-Lin Chung,Yung-Jr Hung,Chin-Ping Yu,
A refractive index (RI) sensor based on fiber-optic Fabry-Pérot interferometer (FFPI) is proposed by splicing an inclined fiber with a SMF. After using etching process to enlarge the cavity, clear interference can be observed. The measured RI and temperature sensitivities of the FFPI are 1334.33 nm/RIU and 37.38 pm/°C, respectively.

32-dB Loss Budget High-Capacity OFDM Long-Reach PON over 60-km Transmission without Optical Amplifier
chenli wei,
For the first time, 33-Gbps 60-km OFDM transmission is demonstrated to show 32-dB loss budget without inline and pre-amplifier. Employing 10-GHz EAM and PIN, the long-reach PON can economically support 32 ONUs with >1-Gbps/ONU capacity.
