GEOMETRİK YAKLAŞIMLA KAZANÇ VE FOTON ÇOĞALMASININ ARASINDAKİ AÇININ HESAPLANMASI

Bu çalışmada daha önce tasarımı yapılmış olup doğrusal olmayan optoelektronik geri beslemeli lazer diyotsistemi için Volterra serisi kullanılarak sistem yaklaşımı uygulanmış ve sıfırıncı derece çözümden foton ( Po ) vekazanç (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 muhtemeldoğrusal bölgeler bulunmuştur. Kazanç ve foton çoğalması arasındaki olabilecek en büyük ve en küçük açıdeğerleri bulunmuş ve bu değerlere karşılık gelen Ith oranı, en iyi doğrusal bölge, doğrusal olarakkullanılabilecek 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.
