“…We should note, that this power splitter is part of a larger structure which is used for sensing applications. 1 Description of the other parts of the structure is beyond the scope of this paper and will be discussed elsewhere. Parts of the structural cross-section parameters are related to the design choice of the larger system.…”

“…for the interferometric readout of phase-shifts in a slow-light sensor. 1 For such a purpose, a device capable of precisely meeting the required splitting of optical power is desired to get a good visibility of the interference fringes, since the light passing through the sensing branch will suffer from large loss as a consequence of the slow-light phenomenon being utilized there. 2 To cope with the fabrication uncertainties and a variety of application, requirements for an actively tunable power splitter is highly desirable.…”

Controllable splitting of optical power with a large splitting ratio range is often required in an integrated optical chip, e.g. for the readout of phase-shift in a slow-light sensor. In this work, we report the modeling and design of an integrated optical programmable power splitter consisting of a Y-junction with a programmable phase-shifter cascaded to a directional coupler. We used a vectorial mode solver, and a combination of a transfer matrix method with a 3D vectorial coupled-mode theory (CMT) to compute the power transfer ratio of a realistic device structure made of Si 3 N 4, TEOS, and SiO 2 grown on a Si substrate. In the simulations, waveguide attenuation values derived from the measured attenuation of a prefabricated test wafer, have been taken into account. Vectorial modal fields of individual waveguides, as computed by a mode solver, were used as the basis for the CMT computation. In the simulation, an operational wavelength around 632.8 nm was assumed. Our simulations reveal that maximum power splitting ratio can be achieved when the directional coupler is operated as a 3-dB coupler with the phase-shifter set to produce a 90° phase-shift. The required coupler length for such desired operating condition is highly-dependent on the gap size. On the other hand, the inclusion of the waveguide loss and the non-parallel section of the directional coupler into the model only slightly affect the results.
