Strong light scattering can make even an optically non-absorbing object opaque preventing deep light penetration. Many far-reaching applications, such as deep brain imaging could benefit from a better coupling of light into scattering medium and increased penetration depth resulting into greater transmission through a highly scattering medium. In this talk I will present a simple, but efficient way of increasing light coupling through optical interface engineering. Capitalizing on our prior work [1-6], we provide a theoretical foundation for our experimental findings and discuss potential applications for chemical imaging and sensing [7-8].
