When the previous studies are compared with each other, it has been determined that the wavelength distance between each mode of MLD should be small. In this context, the optical spectrum analyzer (OSA), which examine the mode spacing, can be used to predict the success of the MLD in the THz signal generation. Thus, in order to be able to choose the most suitable MLD (cheap and compact) to be used in a TDS system, the mode spacing analysis will be sufficed.eninfo:eu-repo/semantics/closedAccesscomplex permittivitymaterial characterizationmode spacingmultimode laser diodeTHztime domain spectroscopyConference Object523520WOS:000467794200097N/A
