Emcore reveals 1550nm and 1310nm InGaAsP DFB laser modules
The firm has launched its indium gallium arsenide phosphide on InP devices for wireless and distributed antenna system applications
Emcore Corporation, a provider of compound semiconductor-based components and subsystems for the fibre optics and solar power markets, has introduced two new Distributed Feedback (DFB) laser modules.
The new InGaAsP 1764 1550nm C-Band DWDM and 1615 1310nm lasers are designed for analogue wireless and Distributed Antenna System (DAS) applications.
adaptation of our highly-linear DFB laser technology for specialised wireless and DAS applications,” says Jaime Reloj, Vice President of Business Development for Emcore.
“Wireless systems providers are building systems in subway tunnels, massive stadiums, high-speed trains and cruise ships. Our new DFB lasers for wireless applications integrate extremely well into these systems, enhancing bandwidth to help enable the delivery of consistent, reliable WiFi signals in areas where interference is high, or signals are normally weak,” continues Reloj.
All Emcore lasers utilise the highly-linear, directly- modulated DFB technology to drive the wide-scale deployment of fibre optics in CATV networks, satellite earth stations and mobile phone antenna sites.
Emcore’s 1764 and 1615 DFB lasers extend that heritage of performance and reliability to today’s demanding DAS applications and are compatible with the 4G LTE (Long-Term Evolution) standard for wireless high-speed data communications over mobile devices.
DFB laser module
The increasing demands on wireless networks from social media, texting, email, and uploading and downloading of applications, music, videos and photos is creating greater and greater need for deployment of cost- effective, integrated wireless DAS systems.
Both the 1764 and 1615 Series laser modules are designed, tested and optimised specifically to support highly-linearised wireless applications. These lasers are matched to 50 Ohm systems typical of wireless networks and have a wide operating temperature range of -40oC to +85oC for reliable performance in harsh node environments and narrow transmitter designs. Both models have bandwidth up to 2.7 GHz.
The 1764 1550 nm C-Band DWDM module features low adiabatic chirp to maximise signal quality over both short and long fibre lengths. The laser’s superior linearity minimises degradation of the broadcast signals caused by distortions and non-linear effects. The 1764 is available in all C-Band ITU grid wavelengths. The 1615 1310 nm DFB module also delivers superior linearity and supports fiber lengths up to 10 km without dispersion issues.

Plasma-Therm Korean workshop addresses multiple semiconductor topics
Workshop attendees came from disciplines as diverse as LEDs, power, photonics, nanotechnology and MEMS participated in the full day event
Plasma-Therm’s advanced plasma processing workshop, held at KANC (Korea Advanced Nano Fab Centre), attracted nearly 100 engineers and researchers from 25 companies and institutes.
Topics spanned the fundamental and advanced technology used in semiconductor device fabrication, materials research, and nanotechnology.
Plasma-Therm, a semiconductor plasma processing equipment supplier, has held more than a dozen one and two day workshops at prominent institutions in Singapore, United States, Sweden, China, and Israel during the last year.
