Black Phosphorus (BP) is a layered two-dimensional semiconductor whose direct band gap can be tuned by layer thickness, enabling broad spectral coverage from the visible into the infrared. 

Unlike many two-dimensional (2D) materials that suffer from indirect gaps, BP offers a true direct gap across multiple thicknesses and high carrier mobility, making it a strong candidate for opto-electronic integration. 

At Iris Light we leverage BP’s unique properties to manufacture our photonic ink platform: the tunable emission/absorption enables “color” control of our films. Compared with other 2D materials (many of which have indirect gaps, poor tunability or limited mobility), BP stands out as a material that bridges materials science and practical device fabrication. This results in nanomaterial films that are engineered for integration into silicon photonic devices, enabling on-chip light sources and detectors with wavelength flexibility and performance edge.

Where Key Semiconductor and Photonic Trends Converge

Our technology sits at the intersection of three transformative trends: silicon photonics, 2D nanomaterials, and heterogeneous microelectronics. By uniting these domains, Iris Light is creating the foundation for scalable, high-performance photonic systems that extend what’s possible in light-based computing, communication, and sensing in classical and quantum domains.
