| dc.description | A reconfigurable multimode interference (MMI) coupler is demonstrated.
The device operates by modifying the phase of the multiple images that are
formed around the midpoint of the MMI section. This modifies the
properties of the following set of images, and light can be directed to a
specific output waveguide, which is therefore ideal to develop a
reconfigurable MMI coupler. In our device the phase change is achieved by
current injection, and therefore minimizing current spreading is crucial for
optimal operation. A zinc in-diffusion process has been implemented to
selectively define p–n regions and effectively regulate current spreading by
controlling the depth of the zinc doping. Using this process, a
reconfigurable 3 dB MMI coupler has been fabricated. Our experimental
results revealed that the device can be easily set to a perfect 3 dB splitter
using only 0.7 mA of current injection. In addition, the device can be
adjusted all the way from a 90:10 to a 30:70 splitting ratio. The results are
very encouraging since, to our knowledge, this degree of tuning of the
optical power has never been experimentally demonstrated in MMI devices.
Furthermore, this concept can easily be applied to a wide variety of
semiconductor photonic switches that operate on MMI effects. | |
