Anritsu Corporation (President Hirokazu Hamada) has started sales from September 20 of its high operation temperature 1310-nm Chip Carrier Type Semiconductor Amplifier AA3T115FYB for use in compact optical transceivers.

This new semiconductor optical amplifier (SOA)*1 features high gain and low polarization dependent gain at high temperatures of 45°C. It incorporates an aluminum nitride (AlN) compact carrier and can be used together with a silicon platform, etc., to configure an optical transceiver*2 with integrated optics.

Anritsu has leveraged its long experience in light-source technologies to develop a wide range of products helping grow optical communications.

Development Background

The explosive growth of data-center networks and Passive Optical Networks (PON) for configuring economic access networks using passive parts has led to widespread use of transceiver modules as key components between different equipment. On the other hand, there is concern about the rapid increase in power consumption accompanying the explosive increase in network traffic, and there is a social demand to reduce the environmental impact of these systems.

To meet these requirements, Anritsu has developed this high operation temperature type SOA based on its experience in optical devices for the communications market.

Product Outline

This chip-carrier type product has a SOA chip mounted on a compact AlN carrier to form an integrated optical circuit. The peak gain is 17 dB at a center wavelength of 1310 nm and operating temperature of 45°C. With its low-power consumption design, the polarization dependent gain is just 1.5 dB (typ.).

Technical Terms

*1 SOA (Semiconductor Optical Amplifier)
This optical semiconductor amplifies external light input by suppressing resonance using anti-reflection films at both end facets of a semiconductor laser. It is compact with low power consumption compared to fiber amplifiers. Although it suffers from polarization-dependency issues, SOA is seeing widespread rapid adoption due to recent design improvements.
*2 Optical Transceiver
This device converts optical signals to electrical signals and vice versa. There are various designs with different package sizes, transmission speeds, optical fiber types, transmission distances, etc.
