Improved the Performance of the Dual Port Pump Laser for Raman Amplifiers

Confirmed the operation at two different wavelengths 和 a consistent optical output power of 500mW from each port.

古川电机株式会社.有限公司. (总部：大手町2-6-4, Chiyoda-ku, Tokyo; President: Hideya Moridaira) successfully improved the performance of the dual port pump laser for Raman amplifiers that is used as the pump laser for Raman amplifiers with high output 和 低功耗.

• Improved the performance of the dual port pump laser for Raman amplifiers
• Possible to freely select the wavelength 和 optical output power of each port, thereby increasing the flexibility when designing Raman amplifiers
• Will exhibit the new product at OFC 2024 scheduled to be held in the United States 和 plan to start mass production during the first half of FY2025

Background

Following the recent appearance of generative AI (Artificial intelligence) 和 machine learning, data traffic at data centers 和 other locations has exploded globally, 预计未来还会进一步增长. 为了应对这种情况, 通信速度需要提高, but there is the issue of decreased transmission distance due to degradation of the OSNR (Note 1) on the signal receiving side. When existing communications systems are used at faster speeds, 拉曼放大器的作用, which can amplify optical output power without attenuation of the signal light quality, 变得越来越重要. 也, because the b和width of the signal exp和s as a result of high-speed transmission, it is necessary to exp和 the b和width to enable high-volume transmission. 因此, Raman amplifiers need to have the flexibility to amplify the light source at a discretionary range based on the selection of the pump laser wavelength. 另一方面, 考虑到扩展成S-, C波段和l波段, 泵浦激光器的数量将会增加, so it will be more important for them to have small size, 输出功率大，功耗低.

Details

The newly developed dual port pump laser for Raman amplifiers confirmed the operation at two different wavelengths (无花果. 2) 和 consistent optical output power of 500mW (无花果. 3)从每个端口. 随着这些进步, it is possible to freely select the wavelength 和 optical output power of the two ports, thereby increasing the flexibility when designing Raman amplifiers. 也, the smaller size of the high-output pump laser contributes to reducing the size of the Raman amplifier 和 overall system.

The successful advances to the dual port pump laser for Raman amplifiers (patented) use our high-accuracy fiber coupling technology 和 optical semiconductor processing technology using InP (Note 2) semiconductor materials developed over the past 25 years, 以及我们独有的低损耗应用, 高效率半导体激光芯片结构.

We will exhibit this new product at OFC 2024 scheduled to be held on March 26-28, 2024, 在圣地亚哥（OFS展位#2041）. 除了, we plan to begin shipping samples from July 2024 和 start mass production during the first half of FY2025.

The current development partially applies the achievement realized as part of the National Institute of Information 和 Communications Technology (NICT) commissioned research “Beyond 5G – Development of extended range optical node technology for realizing ultra-high speed, 大容量网络”（关键问题045）.

展望未来, 继续发展高产, low-power consumption laser chip technology 和 contribute to accelerated reductions in module power consumption 和 the establishment of environmentally friendly networks.
