Low-Phase-Error Silicon 90° Optical Hybrid with Large Fabrication Tolerance

A novel silicon 90° optical hybrid with large fabrication tolerance for the phase error is demonstrated. A high yield of 99.94% for| phase error| < 5° in the wavelength range of 1.525 - 1.57µm is achieved by using two fabricated wafers.
