To break through this bottleneck, researchers are trying to
integrate photonics into silicon
devices.
«In this way, the switch chip achieves polarization «insensitivity» without doubling the size and cost of the chip, which is important for broadening the practical application of such
photonics integrated devices, said lead author Ken Tanizawa of AIST.
The new
device, referred to technically as a «fully
integrated non-duplicate polarization - diversity silicon -
photonic switch,» consists of a single 8 x 8 grid of 2 x 2 element switches.
These sources are fabricated on a compact, silicon - based
integrated photonics platform, which enables hundreds of
devices — in this case, frequency combs — to be fabricated on a single small - area die.
This is exciting for
integrated photonics because most optical
devices use interactions between two or more waves, which need to propagate in sync as they move through the circuit.
Bob Deri's technical scope spans fields such as
photonic devices, micro-fabrication, communications systems and interconnects,
integrated electronics, hardware, large laser systems and microwave diagnostics.
The
devices, called optical isolators, may help solve major data capacity and system size challenges for
photonic integrated circuits, the light - based equivalent of electronic circuits, which are used for computing and communications.
