The design and analyze of three MZI and a Double-MZI with different phase-shift is presented.

Circuit desing Implementation:

The technology used for constructing the circuits is from Australian Silicon Photonics (ASP) PDK. A standard waveguide template and directional coupler from ASP were used. AutoPlaceAndConnect was used to hookup all the circuits. Analyze the circuit:

• First MZI delay length $\Delta L_1 = 15 \mu m$
• Second MZI delay length $\Delta L_1 = 150 \mu m$
• Forth MZI* delau length $\Delta L_1 = 0.337 \mu m$

• The fourth MZI designed to form an MZI that performs resonance at wavelength = 1.55 µm

• Power coupling for the directional couplers: 25%, 50%, 75%
