In recent years, the optical communication industry has developed rapidly, and the competition is also very fierce. Under the environment of all-optical network sweeping the world, major manufacturers continue to improve their own technology, while trying to reduce costs to maximize profits. As the core part of active optical devices, lasers occupy most of the cost of optical devices, and play an important role in reducing the cost of optical communication systems and optical devices. Only by reducing the cost of the laser can the laser be applied on a large scale. How to reduce the cost of lasers is also a matter of great concern to major optical communication equipment manufacturers. As a result, lasers that are low-cost and can be used on a large scale have become the most urgent need for optical device manufacturers.

Therefore, low-cost and large-scale application of lasers has become the most urgent demand of optical device manufacturers, which will also be the development trend of the future market, so as to promote the development of the entire industry chain.
On September 8, 2009, a seminar on the promotion of new laser products was held in Shanghai Science Hall, which was delivered by Dr. Cai Bo, vice president of EblanaPhotonics company. Dr. Cai introduced a DM series laser developed by EblanaPhotonics company. The series laser uses the existing semiconductor process technology, through some groove processing, gain the required wavelength, and resist the useless wavelength, so as to achieve a single mode of operation. This series of lasers can replace the existing DFB and FabryPerot lasers. Its advantages are no isolator, high reliability, good consistency, production cost can be reduced by more than 2/3, it is easy to realize a single mode at any wavelength, and flexible advanced packaging technology. The large-scale commercial use of the laser will greatly reduce the cost of fiber-to-the-home devices and speed up the process of FTTH.
