RTI of VCSEL the Vertically radiating lasers

2018: Start of the line of production of the vertically radiating lasers

On August 2, 2018 it became known that the RTI concern starts a production line on production of the vertically radiating lasers (VCSEL). Development of RTI will allow to transfer data on fiber optic networks with speed to 30gbit/with with range to 10 km. on one channel. It means reduction for fiber optic telecommunications much of costs for laying of fiber optic networks, or a possibility of increase in capacity of already laid lines several times.

Superficially radiating lasers with the vertical VCSEL resonator are key components for high-speed optical links of data transmission in telecommunication. Thanks to diminutiveness, a low threshold current of generation, low power of consumption, energy efficiency, smaller temperature dependence and also a possibility of testing of devices on a plate, devices based on VCSEL intensively develop in Russia and in the world.

In May, 2018 with assistance of RTI the equipment was delivered to the enterprise of group of JSC OKB-Planeta and process of start of a production line on production of the vertically radiating lasers started. The OKB-Planeta enterprise will be capable to produce hundreds of thousands of pieces a month that completely will cover requirement of the Russian market of telecommunication.

One of the main economic parameters in telecommunication – the cost of transfer of information unit in relation to distance. In 2015-2016 research work during which it was proved that by means of use of long-wave VCSEL it is possible to reduce this cost several times was carried out to RTI. In the course of works about 10 thousand samples of crystals of VCSEL which showed excellent technical characteristics were made. In 2017 engineers of RTI based on the German laboratory carried out works on packaging of the received samples. The received characteristics of lasers after packaging showed that in difference from the short-wave VCSEL (850 nanometers) working at a distance no more than 300 m, VCSEL of 1550 nanometers. it is capable to transfer data with speed more than 25 Gbit / c to distance to 2 km, and when processing a signal using a mathematical apparatus and to 10 km. Separate lasers showed a possibility of data transmission with a speed up to 30 Gbps. Thus, korpusirovanny Russian VCSEL-1550, successfully passed basic laboratory tests.

As of August, 2018 in OKB-Planeta work on industrial commercializing the production process on agglomeration of epitaxial wafers and their subsequent processing began. Process of agglomeration is one of key technology processes by production of long-wave VCSEL. Production of epitaxial wafers is executed also by the company of group RTI of Konnektor Optiks LLC.

Thus, RTI can enter the Russian market with products of a world class in telecommunication area and provide to telecom operators successful development of fiber optic networks regardless of foreign supplies of equipment.

Long-wave VCSEL has every chance to become key component equipments of modern local telecommunication networks. The most widespread standard of transceivers in fiber optic networks are SFP or QSFP transmitters in which lasers the type FP, DFB or VCSEL are installed. But use of VCSEL was considerably limited to the fact that in large quantities VCSEL made in the world with the wavelength of 850 nanometers., had in the range several relatives to 850 nanometers. lengths of waves were also not suitable for multi-slot data transmission in the QSFP standard with wavelength division multiplexing. The made RTI of VCSEL of 1550 nanometers. radiates in a narrow range that allows to use without restriction it in transceivers with CWDM wavelength division multiplexing already now.

The purpose of RTI is the release on own production capacities of a line of transceivers of type of CWDM4 standard 100Gbase-QSFP28 with a speed of 100 Gbit/sec. and sending range to 2 km., and in near perspective and QSFP28 standard 100Gbase-LR4 with a speed up to 100 Gbit/sec. and wavelength division multiplexing of 4 SWDM channels and sending range to 10 km.
