High-Speed and Duo-Mode 850 nm VCSELs for 47 Gbps Optical Interconnect over 1 km OM4 Fiber
Novel duo-mode 850nm VCSELs with short cavity, oxide-relief and Zn-diffusion apertures are demonstrated to balance the trade-off of speed and reaching bottleneck of VCSELs. Extremely-high data rate (47-Gbps) over 1005m OM4-fiber transmission is reported.

4-Channel ⅹ 10-Gbps Optical Transceiver Using Polymer Waveguide on Flexible Printed Circuit Board
A 4-channel ⅹ 10-Gbps optical transceiver using polymer waveguide is demonstrated on a flexible printed circuit board. The vertical-cavity surface-emitting laser (VCSEL), photo-detector (PD) as well as the transmitter driver IC and receiver amplifier IC are integrated on the flexible printed circuit (FPC) board to show the high-speed optical interconnects. The polymer waveguide combined with a polymer-based 45˚ mirror is used to connect the VCSEL, multi-mode fiber (MMF) and PD. The maximum coupling efficiency between MMF and PD via a polymer waveguide is around 62%. For the high-speed measurement under a 10-Gbps data transmission, the clear optical eye pattern passing the 10-Gbps Ethernet eye mask with at least 15% margin is demonstrated. The bit-error-rate of 10-12 under full optical links is also achieved.

Aliasing-Free Receiving in OFDMA PON Networks Employing Low-Sampling-Rate ADC
The work demonstrates that each ONU can receive a 1/2~1/32 portion of downstream data using an ADC of 1/2~1/32 Nyquist sampling rate. An ONU can dynamically select any portion of downstream data by simply controlling delay time of an ADC. Different ONUs can cost-effectively and efficiently share the access-network bandwidth.

Semiconductor Lasers at Period-One Dynamics for Local-Oscillator-Free Photonic Microwave Down-Converters
Photonic microwave down-conversion using period-one nonlinear dynamics of semiconductor lasers is proposed, which provides high conversion efficiency and requires no local oscillators. Experimental demonstration of microwaves at 33.7 GHz down-converted to a frequency ranging from 10 to 14 GHz is presented.

Monolithic Integration of Photo-detector on Silicon Optical Bench with Acoustic Sensing Membrane
A monolithic integration of photo-detector on silicon optical bench with acoustic sensing membrane is demonstrated. Such optical bench integrates with VCSEL, sensing membrane and photo-detector (PD) fabricated by ion implantation approach. The optical efficiency of VCSEL-to-PD is -3.3 dB after integrated VCSEL and sensing membrane by flip-chip bonding. The SNR of photo and dark current is 20 dB.

Fabrication tolerable cladding-modulated Bragg grating reflectors on silicon-on-insulator platform
We propose a fully-etched CMOS-compatible
cladding-modulated grating to allow not only flexible control
of the reflection response but also large fabrication tolerance.
A reflection bandwidth of < 0.6 nm, an extinction ratio of 21.4
dB, and a Bragg wavelength variation of within 1 nm is
experimentally demonstrated.
