Abstract
In this letter, we packaged a DFB laser diode chip and a thin film LiNbO3 modulator chip in a single shell through hybrid integration, and formed an integrated laser emission module. This module exhibits an output power of 15.6mW, an optical insertion loss of 5.60dB, a linewidth of 15.2kHz, a 3dB bandwidth of 36.7GHz. And at 10GHz, it exhibits an 1dB compression point of 13.0dBm, a gain of −39.8dB, an input third-order intercept point of 26.9dBm, and a spurious-free dynamic range of 89.9dB$\cdot $ Hz${}^{\mathrm {3/2}}$ .
期刊介绍：
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
