A multiport passive photonic light circuit chip has multiple waveguides written in at least two layers on a glass substrate. Some waveguides connect transmitting and receiving ports of an optical channel, some waveguides redirect a fraction of optical signals to some other receiving ports, and waveguides have circular cross-sectional shapes wherein a refractive index contrast is in the range of 0.2% to 2%.
