Parasitic reflections can deteriorate the performance of a photonic integrated circuit. This is especially true in circuits containing amplifiers, but even in passive circuits, small reflections can already have a strong influence on circuit\ud performance. It is known that strong reflections can be present when using a 2 × 1 multimode interference coupler (MMI) as a combiner. We investigate methods for reducing these spurious reflections in a generic integration technology. We present a novel MMI shape whose measurements show reduced reflections by 17.5 dB

“…In the FOG, the splitted two beams run through the fiber coil and back to the MMI coupler almost in the same phase. It means that the reflection of the light in the MMI coupler is at the level of about 40-50 dB [12,13] . In our design, the input and output waveguides of the MMI coupler are tapered.…”

An integrated optical chip for fiber optical gyroscope (FOG) is designed and fabricated on GaAs. To achieve a high modulation efficiency and a small chip size, a deeply etched waveguide structure is employed, and accordingly a multimode interference (MMI) coupler is used as the 1 2 power splitter. The size of the chip is about 8.5 mm 0.5 mm, which is much smaller than that of LiNbO 3 -based chips. The experimental results show that the extinction ratio (ER) of the TE mode to the TM mode is over 26 dB and the value of V L of the phase modulators is 18 V cm. The method to further lower V is discussed.

“…This is seen in different regions of the structure. The most notable reflections are the ones seen at the discontinuities between active and passive regions, normally referred to as butt-joint reflections [35], and those in the output coupler [36]. In this investigation only butt-joint reflections are taken into account.…”
