One-dimension (1D) photonic crystals have been widely used in silicon photonics due to its simple structure and multiple working regimes: difraction, Bragg reflection, and sub-wavelength regimes. Due to their periodic modulation of the refractive index they exhibit a band-structure for photons. After summariz-ing the theory of photonic bandgap materials, the preparation and linear optical properties of 1D, 2D, and 3D silicon-based photonic crystals are discussed. The original discovery of Photonic Crystals was reviewed by Yablonovitch in his popular SCIENTIFIC AMERICAN article. This feature results in a spectral region over which no light can propagate within such a material, known as the photonic band gap (PBG).

400G QSFP-DD DR4 silicon photonics modules adopt 100G PAM4 technology, including four parallel channels with a total data rate of up to 425Gbps, four times that of 100G optical modules. This delivers exceptional bandwidth performance, meeting the demands of high-speed data. What began as an academic experiment has evolved into a commercially viable technology powering 100G, 400G, and now 800G optical links across hyperscale, AI clusters, and next-generation data center fabrics. This article provides a comprehensive, engineering-level examination of Silicon Photonics. The Intel® Silicon Photonics 400G DR4+ (Data center Reach 4-lane with extended reach) QSFP-DD Optical Transceiver is a small form-factor, high speed, and low power consumption product, targeted for use in optical interconnects for data communications applications. It uses SiPh chips that integrate a number of active and passive optoelectronic components. A 400G optical module performs photoelectric conversion: With a 400 Gbps transmission rate, these modules support industry evolution from 100M → 1G → 25G → 40G → 100G → 400G → 1T.
