The first chip to integrate laser and photonic waveguide at the same time is a new optoelectronic integrated circuit technology, which can integrate laser and photonic waveguide on the same chip to realize the transmission and transmission of optical signals. The research and development of this chip has important scientific significance and application value, and can play an important role in communication, computing, optical sensing and other fields.

A laser is a device that produces a highly focused beam of light that converts light energy into a laser beam. Photon waveguide is an optical device that transmits optical signals through the chip, and can transmit optical signals inside the chip. Traditionally, lasers and photon waveguides are made separately, and then the optical signal is transmitted through an external connection. However, this method has many problems, such as signal loss, unreliable connection and so on. Therefore, it is of great significance to develop a chip that integrates laser and photonic waveguide simultaneously.

The development of the first integrated laser and photonic waveguide chip needed to solve several key technical problems:

1, material selection and preparation: the laser needs to have high optical quality and high optical response speed, and the photon waveguide needs to have low loss and high optical transmission efficiency. Therefore, it is necessary to select suitable materials and prepare materials with good optical properties.

2, the design and preparation of photon waveguide: photon waveguide is the key device that transmits the optical signal to the inside of the chip, and it is necessary to design a suitable waveguide structure and prepare a photon waveguide with good optical performance.

3, laser design and preparation: laser is the key device to produce laser beam, need to design a suitable laser structure, and prepare a laser with high power and high efficiency.

4, the integration of photon waveguide and laser: the integration of photon waveguide and laser on the same chip needs to solve the coupling and transmission problems of optical signals, and it is necessary to design a suitable coupling structure and achieve reliable optical signal transmission.

The development of the first chip to integrate both laser and photonic waveguide required not only the above technical issues to be solved, but also rigorous testing and validation. Through the verification of experiments and practical applications, the performance and reliability of the chip can be evaluated, and the design and preparation process of the chip can be further optimized and improved.

The integrated laser and photonic waveguide chip has a wide application prospect. In the field of communication, high-speed and large-capacity optical communication can be achieved to improve communication speed and bandwidth. In the field of computing, optical transmission and light processing can be achieved to improve computing speed and energy efficiency. In the field of optical sensing, high sensitivity and high resolution optical sensing can be achieved to improve the sensing performance and accuracy. Therefore, the development of the first integrated laser and photonic waveguide chip has important scientific significance and application value.
