एक साथ गुंजयमान उत्तेजना और प्रतिदीप्ति का पता लगाने के लिए प्रदर्शन करने की क्षमता क्वांटम डॉट्स (QDs) के क्वांटम ऑप्टिकल माप के लिए महत्वपूर्ण है । गुंजयमान उत्तेजना बिना प्रतिदीप्ति डिटेक्शन – उदाहरण के लिए, एक अंतर संचरण माप – उत्सर्जन प्रणाली के कुछ गुण निर्धारित कर सकते हैं, लेकिन आवेदन या माप उत्सर्जित फोटॉनों के आधार पर अनुमति नहीं है. उदाहरण के लिए, फोटॉन सहसंबंध की माप, Mollow triplet का अवलोकन, और एक फोटॉन स्रोतों की प्राप्ति सभी प्रतिदीप्ति का संग्रह की आवश्यकता होती है । प्रतिदीप्ति पता लगाने के साथ बेतुका उत्तेजना-उदाहरण के लिए, बैंड के ऊपर-गैप उत्तेजना-एकल फोटॉन स्रोतों बनाने के लिए इस्तेमाल किया जा सकता है, लेकिन उत्तेजना के कारण पर्यावरण की अशांति फोटॉनों के अंतर को कम कर देता है । QDs के आधार पर एकल फोटॉन स्रोतों के लिए उच्च फोटॉन के लिए उत्साहित resonantly होना होगा, और फोटॉनों के एक साथ संग्रह के लिए उन का उपयोग करना आवश्यक हो जाएगा । हम resonantly को उत्तेजित करने के लिए एक विधि का प्रदर्शन एक एकल QD नमूना की सतह सामान्य दिशा के साथ प्रतिदीप्ति इकट्ठा करते समय नमूने के सट चेहरे से इस गुहा में उत्तेजना बीम युग्मन द्वारा एक planar गुहा में एंबेडेड । ध्यान से गुहा के waveguide मोड के लिए उत्तेजना बीम मिलान करके, उत्तेजना प्रकाश गुहा में जोड़े और QD के साथ बातचीत कर सकते हैं । बिखरे हुए फोटॉनों गुहा के Fabry-टेकनॉलजी मोड से जोड़ा जा सकता है और सतह सामांय दिशा में भागने । इस विधि का पता लगाने ध्रुवीकरण में पूर्ण स्वतंत्रता की अनुमति देता है, लेकिन उत्तेजना ध्रुवीकरण उत्तेजना बीम के प्रचार दिशा द्वारा प्रतिबंधित है । गीला परत से प्रतिदीप्ति उत्तेजना बीम के संबंध में संग्रह पथ संरेखित करने के लिए एक गाइड प्रदान करता है । उत्तेजना और खोज मोड के orthogonality नगण्य लेजर छितराई पृष्ठभूमि के साथ एक एकल QD के गुंजयमान उत्तेजना सक्षम बनाता है ।
