- When the feedback increases, external cavity modes become multimodes and generate the laser noise by random self-mode locking. When the feedback increases further, longitudinal mode hopping or incomplete multimodes appear.1985, Semiconductors and Semimetals, page 80:
- In the multimode graded index fiber, multimodes travel faster as compared to multimode step index fiber.2018, S. C. Gupta, Textbook on Optical Fibre Communication and Its Applications, page 27:
