Dual-Mode Semiconductor Lasers and Their Applications in Optical Clock Recovery and Photonic Microwave Generation

As a compact multi-functional device, monolithic integrated multi-section semiconductor laser has a wide range of applications in optical communication systems and microwave photonics with its advantages in cost, size, power consumption and integration possibilities with other components. In this paper, we will review the design and characteristics of monolithically integrated dual mode semiconductor laser, with special emphasis on amplified feedback lasers (AFL). Then, their application in optical clock recovery and high frequency photonic microwave generation will be discussed
