摘要:

We have fabricated fiber‐compatible, low‐loss, wavelength and polarization insensitive 3 dB 2×2 cross couplers by Ag+‐Na+ion exchange in glass. The couplers were designed using the adiabatic invariance condition for graded‐index channel waveguides. An excellent agreement between theory and experiment is demonstrated.
