TL;DR: In this paper, a monolithic segmented Mach-Zehnder transmitter, fully integrated in a 90 nm CMOS process, exhibits a link sensitivity of −14.1 dBm optical modulation amplitude at bit error rate (BER) = 10−-12 at 12.5 Gbps.

TL;DR: In this paper, the authors present a fully integrated photonic chip spectrometer for near-infrared tunable diode laser absorption spectroscopy of methane (CH4), which incorporates a heterogeneously integrated III-V laser/detector chip coupled to a silicon external cavity for broadband tuning, and a long waveguide element (>20 cm) for ambient methane sensing.

TL;DR: In this article, subtractively patterned Si and SiN waveguides were calculated after each step in the process, and it was found that adjusting the ratio of CF4:CHF3 during the hard mask open step produced reductions in LER of 26 and 43% from the initial lithography.

TL;DR: 50- and 60-Gb/s hybrid-integrated optical links in the O-band with CMOS photonic components driven by silicon–germanium ICs using optical-domain feed-forward equalization are reported, providing a promising path toward extending speeds in latency sensitive optical links.

TL;DR: In this article, an integrated photonic circuit is attached to a semiconductor substrate, and the optical gain chip is optically coupled to the Integrated Photonic Circuit thereby forming a laser cavity.
