Abstract

In this study, system approach is applied by Volterra series for the previously designed non-linear optoelectronic feedback laser diode system. Photon ($P_o$) and gain (g) equalities are obtained from zero order solution and are used for the geometrical approach. The relation between gain and photon population is determined according to threshold current ($I_{th}$) for possible linear regions. The maximum and minimum angle and the corresponding $I_{th}$ ratio values are computed. The optimum linear region, maximum $I_{th}$ ratio for linear usage and the corresponding $I_{th}$ value where the saturation point begins are also determined.

Özet

Bu çalışmada daha önce tasarımı yapılmış olup doğrusal olmayan optoelektronik geri beslemeli lazer diyot sistemi için Volterra serisi kullanılarak sistem yaklaşımı uygulanmış ve sıfırıncı derece çözümden foton ( $P_o$ ) ve kazanç (g) eşitlikleri elde edilmiştir. Bu eşitliklerden elde edilen eğriler geometrik yaklaşım için kullanılmıştır. Geometrik yaklaşımla kazanç ve foton çoğalması arasındaki ilişki eşik akımına ( $I_{th}$ ) bağlı olarak muhtemel doğrusal bölgeler bulunmuştur. Kazanç ve foton çoğalması arasındaki olabilecek en büyük ve en küçük açı değerleri bulunmuş ve bu değerlere karşılık gelen $I_{th}$ oranı, en iyi doğrusal bölge, doğrusal olarak kullanılabilecek en büyük $I_{th}$ oranı ve doyum noktasının başladığı $I_{th}$ akım değeri tespit edilmiştir.
