Coupling ratio tuning of direct UV-written X-couplers for cascaded power splitters in WDM networks
We present a study of low polarisation sensitivity 2 degrees X-couplers with 20% coupling ratio tuning via refractive index asymmetry, attaining 50:50 power splitting at 1550nm. The device has less than 5% coupling ratio variation over 30nm in the C-band and <0.7dB polarisation dependent loss.

Abstract

We present a study of low polarisation sensitivity 2 degrees X-couplers with 20% coupling ratio tuning via refractive index asymmetry, attaining 50:50 power splitting at 1550nm. The device has less than 5% coupling ratio variation over 30nm in the C-band and <0.7dB polarisation dependent loss.
