Four-channel arrayed polarization independent EA modulator with an IPF carrier operating at 10 Gb/s

We have developed a four-channel 10-Gb/s electroabsorption modulator array. We have introduced an innovative technique with an impedance-matched film (IPF) carrier to feed the electrical driving signal. The IPF carrier is made of an insulating polyimide film on which a coplanar waveguide is formed. We have achieved 10-Gb/s operation for all channels with clear eye opening and with negligibly small crosstalk. Polarization independence is confirmed for each arrayed channel.
