“…To decrease packaging complexity, high-efficiency, perfectly vertical grating couplers would be the key to promoting the integrated hybrid silicon-based VCSELs. Besides, perfectly vertical grating coupling [27][28][29][30], which enables fiber packaging without angle polishing, can be very useful to decrease the fiber packaging cost [31][32][33].…”

We propose and numerically demonstrate an 800 Gbps silicon photonic transmitter with sub-decibel surface-normal optical interfaces. The silicon photonic transmitter is composed of eight silicon Mach–Zehnder optical modulators and an interleaved AMMI WDM device. This WDM device comprises two 1 × 4 angled MMI and a Mach–Zehnder interferometer (MZI) optical interleaver with an apodized bidirectional grating which has about −0.5 dB coupling loss. Both the Mach–Zehnder electro-optical modulators and MZI optical interleaver regard the bidirectional grating coupler as vertical optical coupler and 3-dB power splitter/combiner. By importing the S-parameter matrices of all the components which have been carefully designed in simulation software, the circuit-level model of the optical transmitter can be built up. On this basis, the static and dynamic performance characterization were carried out numerically. For NRZ modulation, the optical transmitter exhibits the overall optical loss of 4.86–6.72 dB for eight wavelength channels. For PAM4 modulation, the optical loss is about 0.5 dB larger than that of NRZ modulation, which varies between 5.38–7.27 dB. From the eye diagram test results, the WDM silicon photonic transmitter can achieve single channel data transmission at 100 Gb/s NRZ data or 50 GBaud/s PAM4 symbol rate with acceptable bit error rate.

“…Considering that the silicon-based 54.7 reflective mirrors apply for the out-of-plane optical coupling, a high coupling loss between waveguide-to-waveguide in the vertical direction (using two 54.7 reflective mirrors) [16] or between vertical-cavity surface-emitting laser (VCSEL)-to-fiber (using one 54.7 reflective mirror) [19] was suffered due to laser beam walk-off at the receiving waveguide [16] or the flat-facet fiber [19]. The 45 reflective mirrors could provide an out-of-plane optical coupling with a reflective angle of minimum deviation [17], [18], [20]- [25].…”

A polymer-waveguide-based optical circuit with two vertical-transition output ports for the optical interconnects is demonstrated on a silicon substrate. Such a 1 Â 2 vertical splitter is realized using a polymer waveguide monolithically integrated with three silicon 45 microreflectors. The vertical-cavity surface-emitting laser chip assembled at the input port and two multimode fibers located at two output ports are arranged to demonstrate a two-port optical proximity coupling of the off-chip optical interconnects based on the proposed splitter. The optical insertion loss of À6.6 dB is experimentally obtained for the proposed 1 Â 2 vertical splitter with a splitting ratio of 1.3 : 1. The clearly 10-Gb/s optical eye patterns at both output ports verify that the 1 Â 2 vertical splitter is suitable for the optical interconnects with multiple output ports.

“…Silicon optical bench (SiOB) technology has become a critical solution for aligning micro optical components on silicon substrates in high precision. It has been widely used in a variety of applications in micro optics packaging, such as optical transmitters [1]/receivers [2]/transceivers [3], filters [4,5], switches [6], attenuators [7] and splitters [8], and even in more complex micro optical systems, such as micromachined tunable lasers [9,10], Mach-Zehnder interferometers [11], and Fourier transform spectrometers [12], as well as miniaturized catheters for endoscopic optical coherence tomography (EOCT) imaging [13,14].…”

A novel platinum microheater and comb isolator integrated silicon optical bench (SiOB) assembly method has been successfully demonstrated to provide electrical connection and high precision alignment for a two-axis gimbal-less micromirror. Localized heating and wetting of plastic core micro solder balls is achieved by the integrated platinum heater, and the maximum measured temperature of the platinum heater is about 250 • C. In addition, assembly procedures are significantly simplified by involving a comb isolator made by deep reactive ion etching (DRIE) in comparison with our previously reported design. DRIE is also applied to form a 45 • trench on the lower silicon substrate with a nearly vertical sidewall for the micromirror. Hence, the overall dimensions of the SiOB assembly can be reduced further to meet the requirements of endoscopic optical coherence tomography (EOCT) for miniaturization.
