Websolitary laser diode without feedback. Fig. 3(b) shows the single frequency mode spectrum when feedback is applied with a VHG at several angles (VHG has 35% reflectivity and 4mm length, focal length of collimated lens 4 mm). For the spectrum centered at 404.25nm, the side modes corresponding to the solitary laser diode are suppressed by 15dB but WebOptical injection into a chaotic laser under feedback is investigated for dimension enhancement. Although injecting a solitary laser is known to be low-dimensional, injecting the laser under feedback is found to enhance the correlation dimension D2 in experiments. Using an exceptionally large data size with a very large reconstruction embedding …
Webis the threshold gain of solitary laser given by, = + r f b tho L R R k n c G 1 ln 2 1 (2.4) and G p is the gain of mode p whose wavelength is λ p. G p is defined such that the suppression by mode itself and both p the symmetric gain suppression (SGS) and asymmetric gain suppression (AGS) by other modes q ≠ p are taken into account. WebAbstract: Semiconductor lasers are extremely sensitive to optical feedback, which can cause power dropout events (often called low-frequency fluctuations (LFF)) near the solitary …
WebFeb 1, 1998 · Coexisting attractors, which arise from different external-cavity modes of the same longitudinal mode of the solitary laser, retain distinct stability properties, particularly when the laser is biased far above threshold and subjected to moderately strong optical feedback from a distant reflector. When the laser is modeled by the Lang and Kobayashi … Weba solitary diode laser is usually sensitive to optical feed-back. It was observed long time ago that return beam may induce oscillations that appear in the laser output intensity and their frequency varies with the cavity length, laser de-sign and operating conditions [4]. To achieve single frequency operation, a special wave-
