Öz

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 ( Po ) 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 ( Ith ) 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 Ith oranı, en iyi doğrusal bölge, doğrusal olarak
kullanılabilecek en büyük Ith oranı ve doyum noktasının başladığı Ith akım değeri tespit edilmiştir.

Anahtar Kelimeler

Lazer diyot, geometrik yaklaşım, volterra serisi, doğrusallaştırma, doğrusal olmayan optoelektronik geri besleme.
