semiconductor laser is one of the key components of the next generation optical network.Typical Bragg grating (DBR) tunable semiconductor laser (SGDBR, DS - DBR) has a wide tuning range, such as edge mode rejection ratio and wavelength switching high speed etc, the making craft of this kind of device is more complicated, however, involves the active/passive waveguide integrated, secondary epitaxial growth technology, etc.

In recent years, based on slotted Fabry - Perot (single mode fiber transceiver), the structure of laser caused great interest of researchers, the main reason is that the device has a simple production process, a single epitaxial growth and ordinary lithography process), and is expected to be based on this kind of structure has developed a new, low-cost tunable semiconductor laser.

Professor Yu Yonglin research group optoelectronic device functionality integrated with laboratory research group with Professor L. Barry Dublin City University collaboration on three sections SFP tunable semiconductor lasers were studied. Through detailed characterization of the slot structure constructed device models, simulation results and actual test results obtained coincide. The study not only reveals the tuning mechanism of three sections small form-factor pluggable transceiver, but also has some significance for the optimization design of the device. The study, published in the IEEE Journal of Selected Topics in Quantum Electronics optoelectronic device simulation album (Vol.15, No.3, Sep / Oct, 2013) on.

The research was supported by the Chinese Ministry of Science and international cooperation projects in support of the National Natural Science Foundation of China, Ministry of Education Doctoral Program and the Ministry of Science and Principal Investigator projects in Ireland and Irish Enterprise Partnership project.
