Recently, the need for fifth- and sixth-generation (5 G/6 G) wireless communication technologies that offer enhanced communication capabilities has emerged and developed. As these technologies operate ...
In this Article we propose and experimentally demonstrate PCSELs that enable high-power FM with suppressed amplitude modulation (AM) under direct modulation, and we apply these PCSELs to coherent FSO ...
Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
