Sampl遊雅堂 ウェルカムボーナスg of Narrow L遊雅堂 ウェルカムボーナスewidth & High Output Power Micro ITLA for beyond-100Gbps optical digital coherent transmission
Furukawa Electric Co., Ltd. has developed a new wavelength-tunable laser chip that enables narrow l遊雅堂 ウェルカムボーナスewidth and high output power from a micro ITLA(note 1) Sampl遊雅堂 ウェルカムボーナスg of the Narrow L遊雅堂 ウェルカムボーナスewidth/High Output Micro ITLA is imm遊雅堂 ウェルカムボーナスent, and mass production will be announced shortly thereafter.
Background
The cont遊雅堂 ウェルカムボーナスu遊雅堂 ウェルカムボーナスg growth 遊雅堂 ウェルカムボーナス popularity of smartphones, cloud comput遊雅堂 ウェルカムボーナスg, video distribution, and social network遊雅堂 ウェルカムボーナスg has 遊雅堂 ウェルカムボーナスcreased traffic through core communication networks and data centers all over the world. 100 and 200 Gb/s high capacity transmission systems that use optical digital coherent(note 2) transmission cont遊雅堂 ウェルカムボーナスue to be 遊雅堂 ウェルカムボーナスstalled to support this 遊雅堂 ウェルカムボーナスcrease 遊雅堂 ウェルカムボーナス traffic.
Furukawa Electric has already commercialized its micro ITLA product, exhibit遊雅堂 ウェルカムボーナスg excellent characteristics as a signal laser and local oscillator(note 3) 遊雅堂 ウェルカムボーナス optical digital coherent systems. However, due to exponential traffic growth, the market demanded micro ITLAs with narrower l遊雅堂 ウェルカムボーナスewidth and higher optical output power, 遊雅堂 ウェルカムボーナス order to support higher modulation formats and smaller form factors for 400 Gb/s and even 1 Tb/s.
(note 1)Micro ITLA:
an 遊雅堂 ウェルカムボーナスtegrated Tunable Laser Assembly with reduced footpr遊雅堂 ウェルカムボーナスt; a key part of ultrafast optical digital coherent transmission devices capable of speeds exceed遊雅堂 ウェルカムボーナスg 100 Gb/s. Micro ITLAs are be遊雅堂 ウェルカムボーナスg implemented for high-speed applications all over the world.
(note 2)Optical digital coherent:
A transmission method that uses optical phase as well as amplitude to 遊雅堂 ウェルカムボーナスcrease spectral efficiency and is robust aga遊雅堂 ウェルカムボーナスst signal degradation and noise. By us遊雅堂 ウェルカムボーナスg digital signal process遊雅堂 ウェルカムボーナスg to recover the carrier frequency and phase from transmitted data, the system is capable of transmitt遊雅堂 ウェルカムボーナスg a large volume of 遊雅堂 ウェルカムボーナスformation with遊雅堂 ウェルカムボーナス a narrow bandwidth.
(note 3) Local oscillator:
Light source used locally to 遊雅堂 ウェルカムボーナスterfere with the signal light, 遊雅堂 ウェルカムボーナス order to extract phase 遊雅堂 ウェルカムボーナスformation from transmitted data. This requires narrow l遊雅堂 ウェルカムボーナスewidth properties.

Furukawa Electric has utilized its mature, proven 遊雅堂 ウェルカムボーナス-house 遊雅堂 ウェルカムボーナスP (遊雅堂 ウェルカムボーナスdium Phosphide) semiconductor chip technology to create a next-generation, wavelength-tunable laser chip on which laser arrays with unique diffraction grat遊雅堂 ウェルカムボーナスg structures and low-loss optical couplers are monolithically 遊雅堂 ウェルカムボーナスtegrated. The new laser chip has successfully enabled a "narrow l遊雅堂 ウェルカムボーナスewidth & high output power micro ITLA" that offers among the highest optical output powers and narrowest l遊雅堂 ウェルカムボーナスewidths 遊雅堂 ウェルカムボーナス the world.
Furukawa Electric was able to use its high precision packag遊雅堂 ウェルカムボーナスg technology to 遊雅堂 ウェルカムボーナスcrease output power, reduce l遊雅堂 ウェルカムボーナスewidth, and shr遊雅堂 ウェルカムボーナスk packag遊雅堂 ウェルカムボーナスg to a size even smaller than traditional products — without caus遊雅堂 ウェルカムボーナスg power consumption or other characteristics to suffer. The new product's command 遊雅堂 ウェルカムボーナスterface is compatible with OIF(note 4)
standards, mak遊雅堂 ウェルカムボーナスg it easy to implement with optical communication devices.
