- In April 2024, Lumentum Holdings Inc., a key player in optical and photonic products, announced the release of its 400G and 800G coherent optical modulator solutions tailored for next-generation data center interconnects. These high-speed modulators support advanced quadrature amplitude modulation (QAM) formats and are designed to improve data transmission efficiency and minimize latency, particularly within hyperscale cloud environments.
- In March 2024, Analog Devices Inc. unveiled its wideband RF modulator chipset specifically optimized for 5G massive MIMO base stations. The new solution supports phase and amplitude modulation schemes with higher power efficiency and reduced distortion, thereby enhancing signal quality across mid- and high-band spectrums in telecom infrastructure deployments.
- In February 2024, Qorvo Inc. launched a series of ultra-linear GaN-based modulators and amplifiers targeting defense and aerospace radar systems. These modulators offer advanced frequency-shift keying (FSK) and phase-shift keying (PSK) capabilities, providing military-grade performance in electronic warfare and airborne surveillance applications.
- In January 2024, Nokia Bell Labs demonstrated a new probabilistic constellation shaping (PCS) modulation technique integrated with its optical modulators, which successfully achieved 1.2 Tbps transmission over a single wavelength during live trials. This advancement aims to meet the surging data demands of 6G-ready infrastructure and long-haul fiber networks.
- In October 2023, Infineon Technologies AG introduced a new line of modulators and demodulators (modem SoCs) optimized for automotive radar and V2X (Vehicle-to-Everything) communication. The launch supports amplitude and phase modulation with ultra-low latency performance, meeting the high-speed requirements of autonomous vehicle systems.
- In September 2023, Mitsubishi Electric Corporation launched its next-gen satellite modulators equipped with dynamic polarization and phase modulation techniques. These were deployed as part of Japan’s national satellite communication program to enhance disaster recovery and rural connectivity infrastructure.
- In July 2023, MaxLinear Inc. released its DOCSIS 4.0-compatible digital RF modulator chipset, which supports higher-order modulation formats such as 4096-QAM. This innovation is aimed at cable network operators upgrading their hybrid fiber-coaxial (HFC) systems to deliver multi-gigabit broadband services.
