Hiroshi Hatakeyama,Koichi Naniwae,K. Kudo,N. Suzuki,Shinya Sudo,Satoshi Ae,Y. Muroya,K. Yashiki,K. Satoh,T. Morimoto,K. Mori,Tokuhito Sasaki +11 more
TL;DR: In this paper, the first demonstrated near-complete coverage of the S-, C-, and L-bands using six different ranges of wavelength-selectable microarray light sources (WSLs) based on a distributedfeedback (DFB) laser diode (LD) array.

Growth pressure dependence of neighboring mask interference in densely arrayed narrow-stripe selective MOVPE for integrated photonic devices
Shinya Sudo,Yoshitaka Yokoyama,Tadashi Nakazaki,K. Mori,Koji Kudo,Masayuki Yamaguchi,Tatsuya Sasaki +6 more
TL;DR: In this paper, the dependence of neighboring mask interference on growth pressure in narrow-stripe selective MOVPE with arrayed stripe masks for the growth of densely-arrayed optical waveguides was investigated.

First demonstration of novel active multi-mode interferometer (MMI) LDs integrated with 1st order-mode permitted waveguides
Kiichi Hamamoto,Jan De Merlier,Masaki Ohya,Kazuhiro Shiba,Koichi Naniwae,Shinya Sudo,Tatsuya Sasaki +6 more
TL;DR: Although there is no single-mode waveguide region inside the cavity, the novel active MMI-LDs emitted in stable single-transverse-mode output up to maximum output power.

Wavelength channel accuracy of an external cavity wavelength tunable laser with intracavity wavelength reference etalon
TL;DR: In this article, a feedback control scheme for wavelength locking is proposed based on monitoring of the forward output power, and guidelines toward optimization of the etalon are proposed, and experimental demonstration of a channel accuracy of less than 0.6 GHz for a full C-band ECTL with a channel spacing of 50 GHz confirms the high potential of this laser configuration.
