چکیده مقاله :
در اين مقاله يك فرستنده- گیرنده نوري يك‌پارچه مبتني بر تشديد‌گرهاي حلقوي بر روي زيرلايه نيمه‌عايقي InP در طول موج µm 55/1 براي اولين بار طراحي شده است. براي جداسازي طول موج‌هاي دريافتي شامل موج نوري پيوسته و موج نوري مدوله‌شده از تشديدگر حلقوي نوري استفاده شده است. تشديدگر حلقوي داراي ساختار pin بوده که علاوه بر جداسازي طول موج‌هاي دريافتي و ارسالي، وظيفه آشكارسازي طول موج‌هاي مدوله‌شده دريافتي را نيز بر عهده دارند. طول موج پيوسته پس از مدوله‌شدن در مدولاتور حلقوي به سمت يك زوج تشديدگر حلقوي هدايت گرديده تا منعكس شده و به شبكه باز گردد. فاصله كانال بين طول موج دريافتي و طول موج ارسالي (nm 6/1) GHz 200 در محدوده طول موج nm 1570-1520 است. اين فرستنده- گيرنده مي‌تواند پهناي باند حداقل GHz 40 را نشان دهد.
In this article, we designed a novel monolithic integrated optical transceiver based on the ring resonator structure on semi-insulating InP substrate at 1.55 μm wavelength. To separate the incoming continuous (λ2) and modulated (λ1) optical waves from the network, an optical ring resonator is utilized. The ring resonator has the p-i-n layer stack that also detects the incoming modulated optical wave (λ1). The continuous optical wave (λ2) is guided to the ring-resonator based modulator where it is modulated and finally directed toward a pair of ring resonator to reflected back to the network. Channel spacing between λ1 and λ2 is 200 GHz (1.6 nm) at wavelength ranges of 1520 to 1570 nm. This transceiver can illustrate a 40 GHz bandwidth.
