“…The waveguides have a width of 2.9µm in order to get single mode operation. Bragg gratings are obtained by a sidewall corrugation of the waveguide with a periodic pattern as already published by other teams [1]. Reactive Ion Etching (RIE) is used to pattern the waveguides before embedding them in an 8 µm thick PECVD silica annealed at 1050°C under O2 to increase the optical quality of the deposited material.…”

In this paper we present the developments carried out at III-V lab in collaboration with CEA-Leti on the hybrid integration of III-V chips with ultra-low-loss silicon nitride circuits for optical detection and RF systems. Different types of hybrid circuits will be presented: 1-a narrow linewidth laser based on the combination of an InP R-SOA and a long Bragg grating on SiN, 2-a Kerr frequency comb based on a high-power InP DFB laser butt-coupled to a high-Q SiN micro-ring, 3-a long cavity mode-locked laser based on an R-SOA and a SiN circuit with a delay line and a Bragg grating.

“…In 2019, Primiani et al [86] reported a WBG-ECSL with a central wavelength of 1543 nm based on the Bragg gratings and SOA produced by the silicon nitride process. By changing the bias current of the SOA, 0.16 nm was tuned continuously.…”

In this paper, we review the progress of wide tunable Bragg grating external cavity semiconductor lasers (BG-ECSLs). We concentrate on BG-ECSLs based on the wide tunable range for multicomponent detection. Wide tunable BG-ECSLs have many important applications, such as wavelength-division multiplexing (WDM) systems, coherent optical communications, gas detection and atom cooling. Wide tunability, narrow linewidth and a high side-mode suppression ratio BG-ECSLs have attracted much attention for their merits. In this paper, three main structures for achieving widely tunable, narrow linewidth, high side-mode suppression ratio BG-ECSLs are reviewed and compared in detail, such as the volume Bragg grating (VBG) structure, fiber Bragg grating (FBG) structure and waveguide Bragg grating (WBG) structure of ECSLs. The advantages and disadvantages of different structures of BG-ECSLs are analyzed. The results show that WBG-ECSLs are a potential way to realize the integration, small size, wide tuning range, stable spectral output and high side-mode suppression ratio laser output. Therefore, the use of WBG as optical feedback elements is still the mainstream direction of BG-ECSLs, and BG-ECSLs offer a further new option for multicomponent detection and multi-atoms cooling.
