- For 40GBASE-LR4 application, we designed and fabricated a 4 × 10-Gb/s CWDM receiver optical subassembly (ROSA) module integrated with a collimator, an optical demultiplexer (DMUX), and a TO part. The TO part includes focusing lenses, photodiodes (PDs), transimpedance amplifiers (TIAs), and high-speed TO header. The optical DMUX has insertion loss of -1.2 dB and adjacent crosstalk of less than 30 dB. The focusing lenses in the TO part show aspherical lens shape and provide high alignment tolerance of more than 짹300μm for single and array lens types. Especially, electrical crosstalk was less than -40 dB and optical crosstalk was negligible in the TO part. The developed 4 × 10-Gb/s ROSA module shows 3-dB OE bandwidth of about 9.1 GHz GHz and an average receiver sensitivity of -17.7 dBm for four channels at extinction ratio of 6 dB and bit error rate of 10-12. © 2010 IEEE.
