“…24,25 ) About a 10% loss in optical power was observed for modern InGaAsP laser diodes emitting at 1.3 μm after a room-temperature gamma dose of 10 3 rad. 26 Doses up to about 10 7 -10 8 rad of γ-radiation do not cause catastrophic failure of laser diodes, 17 and laser diodes which are designed for high power and high speed (for use in data transmission lines) show only small reductions of light output power up to 60 Co gamma doses of 10 8 rad.…”

“…For example, in the InGaAsP laser diodes mentioned above, there was no degradation in optical power when irradiation occurred at 200°C. 26 Semiconductors undergo transient photocurrents from intense gamma-ray pulses from nuclear weapons (typically 10 6 to 10 12 rad(Si)·s -1 for a duration of less than 1 ms). 28 The electron-hole pair concentrations generated by a pulse with a dose rate of 10 9 rad(Si)·s -1 are as high as 10 18 cm -3 , well above most semiconductor doping levels.…”

The effects of ionizing and neutron radiation on the characteristics and performance of laser diodes are reviewed, and the formation mechanisms for nonradiative recombination centers, the primary type of radiation damage in laser diodes, are discussed. Additional topics include the detrimental effects of aluminum in the active (lasing) volume, the transient effects of high-doserate pulses of ionizing radiation, and a summary of ways to improve the radiation hardness of laser diodes. Radiation effects on laser diodes emitting in the wavelength region around 808 nm are emphasized.3

Semiconductor laser diodes (LDs), with merits of little volume, lightweight, low power consumption, ease of modulation, and high data rates, are great candidates for space laser communications. However, operating in a radiation environment can result in various damages to LDs. Hence, the growing focus on satellite laser communications necessitates LDs with improved radiation hardness. This review covers the efforts made in investigating the radiation effects on LDs induced by various types of radiation, including neutrons, γ-rays, protons, electrons, and other radiation particles. The conditions of radiation experiments and the behaviors and mechanisms of the degradation of LD material and device performance after being radiated are surveyed and discussed. It has been revealed that quantum dot (QD) LDs typically exhibit superior radiation tolerance compared to quantum well LDs or LDs with bulk active layers due to the enhanced confinement of carriers and reduced active areas in QD LDs, indicating significant potential for space applications. Furthermore, current challenges and issues in this field are discussed and addressed, providing a perspective and outlook for further research. Our review aims to guide the development of suitable light sources for future space laser communications, fostering high-performance satellite communications networks.
