Single photon counting detectors are extremely important in the evolution of quantum technologies. The existing devices for the low-flux measurements are bulky and their implementation cannot be made with small footprints. Integrated photonics aims to allow the miniaturization of these setups. We present simulation results for the design of a single 1x10 multimode interference coupler (MMI) in terms of the power imbalance between the output waveguides, optical losses, and tolerance on the operating wavelength. This component acts as the fundamental building block of a photonic integrated circuit (PIC) in the TriPleX platform, acting as an optical divider that is able to bring down the power to ratio levels of 1:10 -5 . The central operating wavelength is 850 nm. This PIC is based on five cascaded 1x10 multimodeinterference couples (MMIs) in a novel function for bringing the power to an exceptionally low, and consistent level with repeatable and reproducible results. The fabricated photonic chips have been characterized in lab settings. The two bestperformed PICs have been packaged and incorporated in a laboratory setup with embedded reference standards for optical power measurement in a technique referred to as "self-calibration". They were tested in system settings, where they successfully demonstrated that we have achieved a linear splitting ratio of 1:10 -9 by cascading nine splitters.

Optical communication systems are expanding from the conventional point‐to‐point system to the mesh‐type network systems for subscribers. As a result, the requirement for passive circuits such as optical divider, optical combiner, and optical switch is increased. Since optical waveguide‐type circuits have superior stability and mass producibility, they are considered important for construction of future optical communication systems. This paper describes development of the planar lightwave circuit (PLC) technology using the silica‐based waveguide on a silicon substrate. In the first half, the design technology of the silica‐based waveguide, the design and production examples of PLCs, and the system experiment examples are introduced. In the latter half, the latest tendency of high‐density integrated PLCs is emphasized based on the use of the high relative refractive index difference (high‐Δ) with a view to large‐scale PLC, and the characteristics of the high‐Δ waveguide and examples of its applications to high‐density integrated optical circuits are presented.
