چکیده

در این مقاله خواص نور کند در یک موج‌بر بلور فوتونی با نقص خطی بررسی شده است و برای بهبود مشخصه‌های نور کند از تکنیک تزریق سیال نوری در حفره‌های هوا استفاده شده است. برای ساختار موج‌بر پیشنهادی منحنی‌های پاشندگی، ضریب گروه و پاشندگی سرعت گروه با روش بسط موج تخت دو بعدی محاسبه شده است. محاسبات عددی نشان می‌دهد که با افزایش ضریب شکست سیال نوری تزریق شده به حفره‌های دایروی هوا، مشخصه‌های نور کند بهبود می‌یابند.
