Abstract—This article presents a 100-Gb/s four-level pulse-amplitude modulation (PAM4) optical transmitter system implemented in a 3-D-integrated silicon photonics-CMOS platform. The photonics chip includes a push–pull segmented Mach–Zehnder modulator (MZM) structure using highly capacitive (415. These drivers use a proven high volume silicon process technology and support multiple optical platforms including silicon photonics, EML (Electro-Absorption Modulated Laser) and TFLN (Thin-Film Lithi. Therefore, there is a need to solve the problems described above by providing a single-. LOWELL, Mass., March 17, 2026 (GLOBE NEWSWIRE) -- MACOM Technology Solutions Inc. (“MACOM”), a leading supplier of semiconductor products, today announced the availability of its new 448G PAM4 modulator drivers, designed to accelerate time-to-market for next generation 1. (Aloe), a silicon-photonic integrated circuits (PICs) company, will demonstrate the first ever practical use of dual-polarization technology (DP-PAM4) to double the capacity of short-reach fiber links to 425G per lane. Aloe's dual-polarization solution saves the cost, size. ur-level pulse-amplitude modulation (PAM4) driver for silicon photonic Mach-Zehnder modulator (MZM) is pres nted. The driver is designed in a 45-nm RF-SOI CMOS technology and consists of a pre-driver and an output-driver. The pre-driver is made up with scaled, cascaded single-ended CMOS inverter.
