Detailed Solution
Download Solution PDF- फायबर ऑप्टिक नेटवर्क कार्ड्स आणि स्विचमध्ये पिन फोटोडायोड्स वापरतात.
- ते फोटॉन शोधण्यासाठी डिझाइन केलेले आहेत आणि ऑप्टिकल शोधण्यासाठी वापरले जातात.
- प्रकाश संवेदना करताना फोटोडायोडमधून उलट प्रवाह वाहतो.
- जेव्हा फोटॉन उलट-पक्षपाती p-n जंक्शनमध्ये वाहकांना उत्तेजित करतात, तेव्हा प्रकाशाच्या तीव्रतेच्या प्रमाणात अतिशय लहान विद्युत प्रवाह वाहू लागतो.
