Abstract

Two kinds of optical transmitter (Tx) modules using an 1310 nm long-wavelength and an 850 nm short-wavelength 4-channel VCSELs have been fabricated and characterized for comparison. 4-channel VCSEL driver has been fabricated by a CMOS 0.18 μm process and used in common for the fabrication of both modules. Both of the modules showed less than 1 x 10-12 of bit error rates (BERs) and clear eye openings at the speed of 2.5 Gbps and 3. 5 Gbps. 3dB bandwidths of the two different Tx modules of 850 nm and 1310 nm VCSELs are 3.76 GHz for 850 nm VCSEL and 3.80 GHz for 1310 nm VCSEL. The optical crosstalks of the both transmitter modules are less than -50 dB in common. Crosstalk evaluation of the two optical interconnection systems using these two Tx modules shows that the application of the 1310 nm wavelength VCSEL as well as 850 nm wavelength VCSEL for the optical interconnections is expected to be possible.
